I think you need to re-read Marx, then. I'm not a Marxist, at all, mainly because of the empirical evidence that hardcore redistribution of wealth goes very, very poorly. Frankly it annoys me and worries me that some people associate literally any limit on capitalism with socialism. Adam Smith's invisible hand was driven not by self-interest, but enlightened self-interest.
Putting a hard, generous upper limit on wealth accumulation is not even close to Marxism.
