I do disagree with Marx's solution, even though I do agree, in broad terms, with his analysis. We have to remember what capitalist enterprises were like back then. I ultimately rejected Marxism because he didn't think justice was a real thing, but I do.

By the way, my proposal for a more just economy can be applied to the existing system. It would continue to have the same institutional structure and would continue to function the same way. It would, however, be self-regulating and have no taxes or public debt as well as no unemployment or poverty, and would be more sustainable--all without imposing any cost on employers, without redistributing anything, without imposing any limit on income/wealth, without additional regulations, and without requiring individuals to act any particular way. Full disclosure: there would be a limit on hoarding money, but people and businesses could retain plentiful pools of money and no money would be collected from any person or business before it could be used for consumption or investment.
