First, thanks for a very interesting, ambitious essay.

As it happens, I have found a way to change the existing system so as to end oppression while leaving the system intact. The solution is a "democratically distributed income." It would provide the means to eliminate unemployment, poverty, taxes/public debt, and exploitation while increasing sustainability. In economic terms, it is only a different way of supplying the existing economy with money (as currency). It can be thought of as a kind of permanent 'quantitative easing'. It could be implemented in any nation on the planet, with a single legislative Act. ("Easy as 1-2-3-4" --both links are to articles in Medium).
