Around here they certainly do. They also have housekeepers who clean at least a couple of days a week. And these aren't rich people just people with fairly good jobs.
Banks, law offices, court houses, drug stores, doctor's offices, etc. also pay very well to get their offices cleaned. And it's hard to find people who do a good job (or even show up to vacuum and take out the trash) even when the pay is good.
Detailing cars is another money maker around here and most of that is in CASH, so are home repairs that only take a day or two to finish (NO UNION).
Suck up to independently wealthy people ("evil rich") who have inherited granny's money. They will pay for ANYTHING.
Nobody lives in a richer city over 250k than I do, and I have seen it myself. Sure there’s some top end types left still doing it, but the opportunity is gone to grow in this area.
This reminded me of what happened to my daughter today. She had to attend a safety class and it was held in a rented conference room of a location that advertises how great they are at hosting meetings, classes, etc. Nice building, nice decor- very comfy. She thought the security and cleaning folks were a bit lax though- it seems a stray cat was living under the conference table with her litter of kittens. They all had a good laugh about it- but are you kidding me? There has to be several people at that place that are not doing their jobs for that to happen.
