Oddly,
earlier before I read this I was thinking about the washer/dryer problem in places like Manhattan. Like many such service issue, I suspect there's a basic coordination problem. People really don't need their own machines, but shared machines are a big hassle, as is the laundromat, and washing services are expensive. Figured for large enough apartment/condo buildings hiring a full time person to do wash/fold service would probably make sense.
