@504DR UBI itself is, arguably, one of these workarounds. It's, however, also one of the most elegant workarounds against a whole bunch of abusive features of modern capitalism, even despite all the messiness capitalist systems have.
Working towards UBI systems, popularising the general knowledge about how they work, and about how most of the arguments are just misunderstandings of how macroeconomy works, is probably one of the most useful medium-to-long-term social justice themed political efforts that one can do.
We also need short-term efforts, obviously. UBI will take time. But it's a worthy goal.
Preferential voting of some sort is another valuable goal. There's multiple distinct methods; all have significant benefits over FPV kind of systems.
In the specific contexts of electing multi-seat deliberative bodies through district-associated seat systems, such as UK and USA still use, replacing such systems with proportional voting systems would also be a beneficial change. (Preferential voting, such as IRV or ranked choice, and proportional voting are somewhat complementary; preferential voting fixes issues related to single-seat voting systems; proportional voting fixes issues related to dividing a multi-seat voting system badly into multiple single-seat voting systems.)
I don't know your ideas about revamping the monetary system, but I'd be happy to read about them.
