FDR was famous for saying, "Let's try something: if it doesn't work then we will try something else."
This was pretty much the opposite of Hoover, who insisted that the Great Depression could be solved by cutting government spending.
Republicans try something, like slashing taxes on the rich, and when it fails to work, they do it again, and again, and again. Then they blame toe poor for being poor and take away education subsidies.
Both parties are to some degree pragmatists, but the Democrats are far better at it. Libertarians are strict ideologues. And the wealthy do not give a shit, except they want government help to attain ever greater wealth.
If you don't want to be criticised for misusing the word "utopia", and other words you do not comprehend, do not use them.
