This is precisely what you advocated. The "needs of the state" being the "investment" you call "capitalism." Leftists differ only in deeming that "investment" to be welfare of various sorts. In either case, it's government taking the money and deciding which "investment" is more beneficial to the people in power, the government itself.
Glad to clarify it for you.
Enriching political supporters through legislation "so that their contributors can cash in ( as you put it ) " would not be Fascism.
Sure it would. The STATE confiscates the money. The STATE determines which supporters get the money. The STATE does that to perpetuate the power of those in control of THE STATE.
Love the way you toss out the meaningless phrase "does not optimize..." as if the government EVER optimises anything... LOL
Which is why the fascist political corruption with which you are so enomoured is destructive to wealth and is in no way "capitalist."
