In your constructs all kind of things are fundamental to an economy EXCEPT profits.
Which makes you a particularly beat sort of economist.
Crisis is created by market intervention, amongst other lesser things.
Crisis is created say when; the socialists shoot all the profit producing land owners, as they did in the Ukrainian Holodomor, and then everyone starves to death.
Crisis also arises when the purist Marxian aesthetic - a critical theory forbids & outlaws freedom of speech, so words like hunger or famine are considered inimical to the party ideology and may not be used by the state controlled press. So millions of dumb but uninformed proles starve to death, as they are made incapable of planning their own solutions to the impending doom, as an intelligent free peoples would. Terms like golod/holod should be carved into Marx's dishonourable gravestone, and inlaid in pewter, so people have something to aim at when they gleefully urinate on his disgusting edifice.
