We both want a society where people don't starve and work has meaning. That part is easy. The problem is that communism's answer to that — central planning and state ownership — has a structural flaw that no amount of good intentions fixes.
When you remove prices and profit from the equation, you remove the feedback loop that tells producers what people actually need. A planner in a ministry can't know the local, constantly shifting details of supply and demand. So you get shortages in some places, surpluses rotting in others. That's not a bug; it's the inevitable result of trying to compute what the market computes organically.
And then there's the power problem. If the state owns everything, control of that state becomes the only game in town. That doesn't produce equality; it produces a new elite who decide who gets what. I'd rather have a system where mistakes get corrected by competition than one where mistakes get enforced by decree.
