I have observed that the more money people have they either: 1) have their own washer/dryer and/or 2) have more expendable cash to have their clothes dry-cleaned. Also they tend to value their time vs. money enough to pay the premium vs. go to a laundrymat.

That's a good point. Several places do both.

Also, a lot of commercial places outsource their washing to laundries/laundromats (places that do both)
