Pretty much all of that is false.

The rules I'm expected to follow based on the bottom quintile are generally rules that are no trouble for me to follow.

The taxes I pay support way more than just the bottom quintile. I'm actually in the UK but I guess you're in the US, so here's a rough breakdown based on this infographic: https://en.wikipedia.org/wiki/Government_spending_in_the_Uni....

Much the biggest chunk of US federal spending is Social Security, the great majority of which is pensions. Pensioners are very variable but they're mostly not in the bottom quintile. Then "nondefense discretionary" spending which is a mixed bag but again is mostly not bottom quintile. After that comes Medicare which again is mostly pensioners. Then defense, which isn't really "to support" any particular subset of the population. Then Medicaid, a lot of which is for poorer people, so I'll give you that one. Then "other" which from the description in the chart is mostly not bottom quintile. Then income security programs, which is probably mostly bottom quintile. If we say that all of Medicaid and income security are "bottom quintile", 10% each of Social Security and Medicare, and 20% each of "nondefense discretionary" and "other", go to support the bottom quintile -- which I think is probably all on the generous side -- then that comes to about $1.56T out of $6.1T of spending, or out of $5.5T if you prefer not to count debt servicing.

The greatest risks to my life and property are from disease (for my life), wear and tear plus accident (for my physical property), and stock market instability (for my investments). None of those things has much to do with the bottom quintile.

In the US, homicides are about 0.02% of deaths, and most of those happen to people within that bottom quintile you evidently resent so much.

The dearth of comfortable public spaces is because you have to allow the bottom quintile to be there and not-bottom-quintile people like you want to make those spaces as unwelcoming to them as possible even at the cost of making them less comfortable for everyone. And also because your society has failed to provide the bottom quintile with better places for the things you don't like them doing than those public spaces.

It may well be true that zoning laws are developed for fear of the bottom quintile. You might want to consider the possibility that the fear is as much of a problem there as the bottom quintile itself.
