Destruction of the system and building a new fairer one. Similar to how feudalism gave way to capitalism, things can improve. What details are you wanting to know exactly?
An egalitarian society where the means of production are owned (or mostly owned) by the working class. A blend of that and small private industry with heavy regulation would be nice. I like how the Kurds in Rojava are trying to build things but it's impossible to know how successful their ideas could be while they're dodging bullets from Syria and Turkey. The Zapatista movement is another way of doing things I'd consider.
