If you’re in the majority, you have the votes to be able to accomplish something with reform. It’s not like we live in a monarchy, reform is possible under our system.
In several countries we actually saw this happen: Sukarno in Indonesia, Allende in Chile, Lumumba in DRC, etc.
What happens is, under our system, the United States will come and fucking kill you for daring to attempt things like land reforms and then install a dictatorship to commit mass torture and murder and worse.
So maybe, after the hegemon collapses, it might actually be possible to reform our way to communism. Unfortunately under our system the empire exists and it is hungry.
