Everything that they told you about capitalism was a lie

Private Ownership

"Capitalism" is not the system that introduces private ownership. Actually, the system that introduced private ownership was the rebellion against both European nobility and the Vatican, both of which attempted to make legal claims of authority over the land that the peasants and meager houses/businesses of the middle ages ran for themselves. This concept of "private ownership" was stimulated by the Enlightenment idea that government and religion shall have no say in what you do in private, and that they have no higher claim to ownership ultimately because this "divine right" thing is utter bullshit. This leads to the bicameral legislation in England. It does go back before England (see: bicameral legislation in Germany and the anti-Vatican sentiment there, as one of the few kingdoms that fought the Vatican for their own sovereignty), but that is where it forms into the more modern concept of it.

Corporations

"Capitalism" is the legal introduction of wealth being pseudo-sovereign, which means the holders of the wealth (the corporations that they were collected in, not the individuals) were pseudo-sovereign. The real beginnings of capitalism are the Dutch East India Company (founded 1602), the first stock market (also 1602), and then the move to Britain (William of Orange's invasion funded by Venetian financiers), leading to the British East India Company, abrupt ends of royal succession (see: English Civil War, the Bavarian Saxe-Coburg-Gotha house becoming House of Windsor, the "Black Nobility", etc), and the British-backed Opium Wars in China. The Opium smugglers became the yacht-owning, investment bank-running, Ivy League educated, politician class of the Northeast of the United States. They founded the Skull and Bones at Yale, and they gave major endowments to other universities with that smuggling money as well.

(Adding this fun fact for those who want to make more connections: the Rothschilds originally come from Frankfurt, which is where the "Frankfurt School" was located, which is the nexus of so many so-called "liberal" thinkers that created the society we know today — it is most properly thought of as occultists who infused propaganda into the ideals of Englightenment liberalism and poison-pilled the "Open Society". They also became some of the earliest members of the OSS and then CIA. Frankfurt also stretches across three states: Hesse, Rhineland, and Bavaria. Saxe-Coburg-Gotha is from Bavaria, and House of Hesse is also a player in these games.)

These are the people who have pushed "capitalism" on the United States for the past 100+ years. They have done so under the guise that this is a matter of personal freedom, but we already had the ability to own things privately, and we had no king or church attempting to take our property away.

Every corporation isn't so much an individualist venture as it is a private and collectivist venture. This is a huge and important distinction. This means that as corporations accrue power, they begin to function as "states within a state". They have administration, economic productivity, finance, royals (the majority owners are essentially the "royals" for a given corporation). They are well-organized and do NOT pursue individualist goals, because once again, they are not individualist ventures. However, they do not have to answer to the public, nor even to government for the most part. Once they have coercive power relative to a municipality, they are effectively reached that size as a "state", and many corporations grow so far beyond that, that they even fund foreign invasions — see: United Fruit Company in Latin America, the heroin traffickers getting us into Vietnam and Afghanistan (who happen to be the same families as the British Opium smugglers from the 1800s!), etc.

Not all businesses are corporations. Mom and Pop stores, diners, tradesmen and contractors are NOT corporations. They may set up various types of business structures under law, and one of these structures actually is a corporation (it's not too difficult to set up; costs maybe $2000 in setup fees), but this is not an essential requirement for the freedom of labor that people ought to enjoy. So once again, this is not about personal rights.

Economic Theory

Economic theory is largely bunk and propaganda. It's a fake field that is currently used by banks to give more power to the banks. That's basically what modern monetary theory is: "banks are benevolent, and we should trust them with running society over even the government itself!" And then you look up the functioning of the federal reserve, and the official theory is "We can't trust the government to govern these banks! The banks have to do it themselves!" It really is this ridiculous and stupid.

I won't say much about communism because I'm not an expert on it. I do believe that communism is the genuine enemy of these globalist-capitalist-bankers, but aspects of it have been perverted and infiltrated so that the bankers can still get their way. The real "benefit" of communism in the countries that originally practiced was solely that they were developing a measure of sovereignty against the globalists who wanted to infiltrate their markets and control them from abroad. It amounts to isolationist economics, but you also don't need communism to achieve this, and there are many nasty sides to communism that show it's really not all that good of a system either. But like a drug that has side effects, it was good for those who wished to cure themselves of the globalist system badly enough.

There are other major economic theorists that you should be aware of instead. You should be aware of Henry Clay, the American System, and the American School of Economics. This was Abraham Lincoln's idol, and that ideology may have indirectly led to his death (if the assassination was caused by Lincoln printing greenbacks). The American School is basically: government should subsidize infrastructure, government should protect local industry with tariffs (ie, it is AGAINST Adam Smith's principle of comparative advantage, which is most beneficial to the mercantile state running the global market), and government should print its own money (NOT a private federal reserve which creates debt between the government and banks simply for money creation, but money creation which is debt free because the government is sovereign and therefore is not required to pay third party to authorize said money creation).

You should also be aware of Henry George. He is a good one to bring up to people who see some value in communism in terms of the actual ownership of capital. George focuses primarily on land and envisions a different way of taxing it, so that you avoid the rentier-style businesses that provide no value to society but make the most money. His primary idea is the Land Value Tax.

People need to be aware of these alternatives because most uneducated folk are stuck in this dialectic of communism vs capitalism, and the terrors of communism make our current privately owned slave state seem nice. There are better ways.
