If we voted with money in The US, then almost all of the lower class has no vote.
Even if they all voted together as a solid block.

This is how it works... right now.
Democratic republic is hacked beyond repair.
The lower class controls nothing.
1 person : 1 vote is not really a valid way to get consensus as most people are uneducated on the necessary material and can be easily manipulated... and then the people that "represent" them can do whatever they want once elected.

I could go on about what I think the fixes are here but it would turn into a book.
