i mean, don't city councils also find it highly revenue-enhancing to encourage the replacement of older housing stock and long time owners with new, high priced, units?
The point remains that both groups of workers are essential to have in close proximity.
It may not work for everyone, but where housing is in short supply, and the demand for labour is great, a working dorm/camp setup for those forced to be working homeless might be helpful.
You can make $150/hr, if your living expenses work out to $140/hr you're not making (or keeping) much.
Like co-working, maybe other setups like co-housing setups might need to come up. They obviously may not work for everyone including families.
If COL in an area is so high that essential personnel can't afford to live within 100 miles or reasonably commute there, it seems to me like the sort of circumstances that lead to a company moving to a more affordable area.
