When did it take away citizens right to vote? You're talking about felons not being able to vote? Yeah I agree with getting rid of that, getting rid of gerrymandering etc. You can be a critic of implementations the system and yet still support the underlying mechanism.
You're supposed to feel like you have a say and not BE in control. Yes minority groups will have less power, that is fine.
"There's nothing making this system better..." "I grant you there are clearly far more freedoms in the western..."
The US will basically spread democracy and capitalism. True capitalism is bad for the entrenched CCP, Russia oligarchs, etc because the US multinationals will inject their capital in the system and take control of everything. Of course they want to keep power. I think there should be some guarantees of the country keeping some ownership over their production.
CCP and Russia are trying to lock down their systems and increase their competitive output, so that when they clash with the West they can compete on value/innovation.
I'm not saying the system is perfect, it's obviously coopted by different groups. But it is as close to perfect as exists in the world today.
