Is it normal america has 3 levels of poor people and too many income brackets?

Why the hell do we have so many income levels? There should not be more than one level of poor, but there is!

Dirt poor
Making 6-9$ an hour
(you better be a highschooler looking for extra funds)
If not you are getting tips, or are a poor immigrant

Very poor 10-13$ an hour
(Can support yourself with 2 other room mates)

Poor 15$ an hour
(Can just barely support yourself)
If you are married though you are probobly living the live of a Low middle class family.

Low Middle Class

19-25$

Have some left over to do fun stuff, While still having enough to pay your bills

30$ up

Medium middle class
(What we think of as middle class)
Your mom and dad probobly own a business
You get name brand clothes, you can throw away money whenever you want(Not rich but richer than most)

35$ an hour

Higher middle class, you can probobly afford a home near the lake

40-50$ an hour

Upper class

(Probably higher management job at office job)
That or you went to college

Than we have rich

Billionaire
Millionaire
Trillionaire

Now, what I think is the biggest issue with the incomes is housing cost. I think if there was more cheap housing available this would not be a problem at all. However the average rent and this is cheap is 600$ a month. THAT IS CHEAP. So anyone who falls under the categories (Dirty Poor, Very poor) can not really survive and are basically going to be homeless workers.
