The currently discussed quorum is 55% of the EU countries representing at least 65% of the EU population. There's a neat voting calculator here https://www.consilium.europa.eu/en/council-eu/voting-system/... where you can figure out how majorities could work or be blocked. It's a pretty reasonable voting mechanism where small countries can block the vote if they group up, but also larger countries with substantial share of the population can as well.
Fact remains that larger countries with larger populations carry a larger weight - but individual countries can't hold the EU hostage any longer (Even Germany with the largest population share can't block a vote alone)
Also, the EU doesn't set taxes. It requires some minimum on specific taxes to prevent a race to the bottom (corporate taxes), but pretty much all taxes are set by the states.
If you have followed Hungary's trajectory under Orban it is pretty obvious that there are corruption issues. Not that Hungary is the only country affected, it's just the most obvious
Once some of the EUs more insane policies are forced on countries the desire to leave will spread.
> Veto rule is no way to govern a large group, since you only have to bribe a single member to cripple the whole.
Are you saying there is a corruption issue right now?
With majority rule (size TBD) a handful of countries will ride roughshod over others. Enjoy centrally set tax rates
