The last problem alone is perhaps the hardest to solve.

Governments and corporations behave a lot like entities of their own, apart from the humans supporting them, and subjected to natural evolution: some entities die, and aspects of the surviving entities multiply.

And, while they can be killed multiple ways, common ways boil down to:

• it picked unnecessary fights against other entities
• it was unable to gather support from other entities for its own survival

As a net result, govs became damn good at allying themselves to corporate interests, and corporations became damn good at supporting governments against their own citizens. To solve this shit you’d actually need to flush most governments and corporations out, like killing all the weeds from your garden. As in, world revolution.
