I think liberalism leads to capitalist status quo, not communism. At least American liberalism. But I do agree they're both functionally the same party and same master.
When you really take a look at American policies there is nothing close to communism. Federalism is not communism and really cannot be communism. Social policies can be inspired by communist or socialist ideals but they're done under the careful guise of capital control and federalist control.
They are both the same thing, they have both lead to the same ends here.
Federalism just tricked everyone onto declaring they live on a federal commune, instead of in a free State.
And that they owe a quota of production to the federal commune because everything belongs to the state and is only given to you as a public office.
