You brought up politics in relation to different economic class.

My point was how we treat ultra wealthy as a political issue is independent from the underlying reality. They aren’t directly outvoting poor people to revive more benefits, it’s instead a question of influence.

Billionaires tend to see positive ROI from getting involved in politics, which is self reinforcing over time. But, stepping back you can judge such systems not in terms of current politics parties operate, but in the broader context of how efficient systems are. In that context the ROI is negative for society even if it can be positive for some individuals that comes at significant cost.
