Economic liberalism is the economic theory of both American parties. Idk how it came to be applied to only the democratic party but that's incorrect. OP is presumably critiquing economic liberalism from a leftist perspective, of which the Democrats are not

Right?! This is gaslighting pure and simple. Trump gave tax breaks to his corporate cronies on the backs of the poor and middle class. Was Trump a liberal? How about Bush? Clinton (who was a Democrat) made substantial strides toward fixing the economy. But I guess he was a conservative? Idiots don't know the meanings of words. Next you'll tell us that socialism and communism are both the same thing and what liberals want for the country.
