The rich ones are partying, because he'll tax them less

I don’t know of a reason to assume anyone will pay more federal income tax under Trump, and every reason to assume the bourgeoisie will pay less.

To the capitalist class, higher taxes on the working class is complicated.

First one must understand that your federal taxes pay for nothing because the federal government has infinite money.

Higher taxes on the working class means less profit for the capitalist class from working class consumers. It might mean the working class takes on more debt, which benefits the financial/banking industry. Higher spending by the government means more profit for the capitalist class, but higher taxes on the working class doesn’t necessarily result in higher government spending, because taxes aren’t how the government spends. All federal taxes do is delete money from the economy.
