"We can't have the tax-cattle talking behind our backs about our failures and corruption that fucked up their living standards .. err I mean think of what the far right, pedos and russian spies could do with anonymous messaging, so we'll be banning it to protect our democratic values."
- EU & UK leadership
I completely disagree with your base premise: I think EU leadership (national + EU) performed on an average level over the last three decades, and the EU as an insitution did even better than I would've expected given its limitations/constraints.
If you could pick policies with the unfair benefit of hindsight (while staying somewhat democratically acceptable), what would a "perfect" government have done differently in the last twenty years?
