Let me tell you my experience with communism centralized economy as the alternative.

1. Planned economy = produce as much as possible, more you produce more you are rewarded. It doesn't matter if you make 100x more then it's needed than trow it away. Inefficiency doesn't matter.

2. Ecology ? Foreign westerner propaganda. That there are no fish, animals, half of the plants spiecies disappeared is westerners fault. Emissions ? Nothing can stand in our plan.

3. We produce more than anyone yet people's wellbeing is still behind west? That's not true, there are fascist to the west and it's just western propaganda. BTW if you mention it, you won't see outside for quite while.

Now let me tell you what happened after end of communism.

1. Nature almost recovered because crazy amount of efforts put into it's protection despite it being expensive.

2. If anyone produces more than people need, they ususally go bankrupt or at least are not rewarded for loss. Thus everyone tries to go as efficient as possible.

3. Wellbeing went up 10fold.

I don't know about OP but capitalism seems kinda best option to me ATM
