Trade unions, disaffected intellectuals and state bureaucrats have attitudes in common with monopolistic capitalists, attitudes favourable to planning and state control. This state dominated model can succeed economically but only because of the previous successes of capitalism. Only capitalism can move societies from widespread poverty to widespread prosperity. Once prosperity is attained, a society can move towards socialism if it is willing to accept economic stasis with no future growth. This can be achieved by evolutionary or revolutionary means, though the evolutionary approach tends to be more realistic about what can be achieved in socialism.
