I don’t understand why America can’t do the same and get rid of this ongoing shitstorm?
TL;DR: Because the broken status quo is super profitable and fixing it would mean returning stolen power and eventually wealth to regular people
Longer version:
Because this is what the money and strategy industries behind the politicians want.
If everyone was automatically registered to vote when eligible, many more people would vote.
If many more people, especially from the demographics most hindered right now, voted, the Republican party would cease to be a viable party without changing some basic policy principles.
If the Republican party was no longer viable, Democrats would have no cover for running on Republican light policy positions under the unofficial slogan “vote for us to avoid something even worse”.
If Democrats could no longer do that, the party would split along ideological lines.
With the Republicans gone and the Democrats split with many of them actually left of center, the ultra-rich people bribing both parties as well as the consulting industry selling various blends of status quo or worse strategies as the only options would lose a shitload of power to the will of the actual people.
