Of systems we've proven.

Something has to be tried to be proven, and you have to convince people before doing such.

Blaming capitalism for greed demonstrates a complete lack of understanding of human nature

Allowing human nature to remained unchecked makes us mere animals. Greed must be suppressed, as with lust, envy, and the rest.

Capitalism acknowledges greed and is built to work around it and utilize it

Which is the problem. We shouldn't reward people for taking what is not theirs, but rather encourage them to work for their slice of the pie.

The very fact that globalism inherently includes all countries of all political frameworks proves you wrong.

It doesn't include Nationalist countries, only Capitalist and Socialist ones, which reject the Nation in favor of Materialism.

The solution to problems within capitalism is to fix those problems

That's what Corporatism is: solving the problems of Capitalism, while retaining its benefits. Capitalism wasn't an entirely new system: it built upon the previous systems of Feudalism and Mercantilism.

The reality is that anti capitalism is a cult that is brainwashed into every college student for the last 30 years.

That's Marxism, not Corporatism. You can't lump everything an inch to the left of you as "basically Communism". Marxists actually hate Corporatists more than they hate Capitalists — for these ideologies are both materialist in nature.

most of the proposed alternatives can easily be implemented within capitalist societies

If you change Capitalism, then it's no longer Capitalism.

You can't be free on a communist country and own your own business.

That's true: Communism, and Socialism, is a dictatorship of Labor — and always devolves into a singularity of government control and corruption.

If your alternative requires you to attack capitalism with bullshit then your alternative is not better.

If you criticize anything I like, then you're wrong!

The same way every smartphone that came out after the iPhone was advertised as the "iPhone killer" and inadvertently proved that they were all in fact inferior.

I'd have to disagree with that, as a life-long Android user. The degree to which Apple controls your phone is a deal-breaker for me. I don't want to have to jail-break my phone just to download a politically incorrect app.

Capitalism is simply about freedom, and freedom is everything.

Capitalism is about freedom — but unchecked freedom is just as bad as unchecked authority! I know you aren't an Anarchist, so you can agree that there are certain limits to one's freedoms.

Corporatism is simple about the Nation, and the Nation is everything. The Nation, One Body.
