But some of those interpretations under the individual pillars just weren't even accurate.
Abolition of private property and the application of all rents of land to public purposes.
Americans do these with actions such as the 14th Amendment of the U.S. Constitution (1868), and various zoning, school & property taxes. Also the Bureau of Land Management (Zoning laws are the first step to government property ownership)
Zoning laws and taxes = the abolition of private property? No. Marx wasn't talking about owning a house when he referred to private property. He was talking about the ownership of Capital, and its relationship to the exploitative relationship between those who own Capital, (capitalists, bourgeois) and wage laborers (proletariat). This is the cornerstone of his critique of Capitalism. Basically he viewed any ownership of capital as a form of rent seeking behavior. Property taxes are not the same as the abolition of private property.
A heavy progressive or graduated income tax.
Americans know this as misapplication of the 16th Amendment of the U.S. Constitution, 1913, The Social Security Act of 1936.; Joint House Resolution 192 of 1933; and various State "income" taxes. We call it "paying your fair share".
We don't have a heavily progressive tax system. We have almost exactly the opposite. We have a tax system written by the wealthy for the wealthy. There are literally sections of the US tax code that were written by corporate attorneys. That's supposed to be Communism? I think Marx would disagree.
Abolition of all rights of inheritance.
Americans call it Federal & State estate Tax (1916); or reformed Probate Laws, and limited inheritance via arbitrary inheritance tax statutes.
Estate taxes and the various other forms of taxation that affect a very small minority of cases of inheritance, certainly don't abolish the rights of inheritance. Marx believed in a reset button. Everyone starts from the same point, because there is no generational accumulation of wealth. That is not how American society works.
Centralization of credit in the hands of the state, by means of a national bank with State capital and an exclusive monopoly.
Americans call it the Federal Reserve which is a privately-owned credit/debt system allowed by the Federal Reserve act of 1913. All local banks are members of the Fed system, and are regulated by the Federal Deposit Insurance Corporation (FDIC) another privately-owned corporation. The Federal Reserve Banks issue Fiat Paper Money and practice economically destructive fractional reserve banking.
Marx argued against private creditors. He believed that private loans were the same type of rent seeking behavior as owning private property. Instead of land, the Capital that you would own would be the funds you can lend to whoever wants the credit. But then you argued that all (or most) credit issued in the US is controlled by a private corporation. So how is that communism?
Centralization of the means of communications and transportation in the hands of the State.
Americans call it the Federal Communications Commission (FCC) and Department of Transportation (DOT) mandated through the ICC act of 1887, the Commissions Act of 1934, The Interstate Commerce Commission established in 1938, The Federal Aviation Administration, Federal Communications Commission, and Executive orders 11490, 10999, as well as State mandated driver's licenses and Department of Transportation regulations.
Okay now we're getting somewhere. Transportation is the best example so far. It's also one of the best arguments for any kind of public program. Roads are the perfect example of a public good that should be subsidized. You could also easily argue that almost any form of modern communication can easily, and legally be monitored by the state via the Patriot Act, therefore the State has a more than firm enough grip on the means of communication.
Extension of factories and instruments of production owned by the state, the bringing into cultivation of waste lands, and the improvement of the soil generally in accordance with a common plan.
Americans call it corporate capacity, The Desert Entry Act and The Department of Agriculture… Thus read "controlled or subsidized" rather than "owned"… This is easily seen in these as well as the Department of Commerce and Labor, Department of Interior, the Environmental Protection Agency, Bureau of Land Management, Bureau of Reclamation, Bureau of Mines, National Park Service, and the IRS control of business through corporate regulations.
This is a hard libertarian interpretation of how federal agencies work. The department of agriculture subsidizing farms is completely different than what Marx means by "instruments of production owned by the state." He's literally talking about the State owning farms instead of citizens owning them, because a private citizen owning it is merely rent seeking and profiting from the undeserved ownership of that land.

Private ownership of Capital is a cornerstone of the American economy, and that won't change if Bernie is elected.
Bernie also cannot singlehandedly implement any of the policy proposals in his platform. Presumably we would just see him signing much more moderate versions of his proposals, which can actually be passed through Congress.
