Disagree based on what?

the 99th percentile of wealthy families have a very clear link to politics and political influence

It'd probably be harder to prove they have absolutely 0 link, seriously, of the richest families in the US can you prove they have made 0 political campaign donations? That their donations don't immediately impact policy in the US?

People who own businesses and c suite employees will bring home that range in income... and the businesses they are associated with will donate profits to politicians... which is why you'll see them at political rallies and dinners shaking hands with politicians.

Of course, the 90th percentile of income wasn't what I said, I said 99th percentile.

The corporations overwhelmingly "vote" to further their own interests

While we don't see every single person in the 90th percentiles voting a specific way, they do benefit when their financial interests align with these giant corporations

So ultimately, as the gap between lower and upper classes divides, we do see these groups attempting to gain/hold power. Maybe it's not through politicians, maybe it's through local elections to make sure that no public housing is built nearby, that their tax dollars benefit institutions they've invested into, that the real estate they've invested into doesn't decline in price thus impacting their net worth

Again, it's hard to prove that people at the 99th percentile have 0 connection to politics, but broadly speaking (aka the 90th) it's not just buying politicians

Wealth is being hoarded, it's hard to prove that what I'm saying isn't accurate.
