How about housing in the most expensive and populated ares in the US is a necessity? If there can't be housing available for all the workers in an area then there needs to be a change. Whether it be higher wages, changes in zoning, or public housing depends on the area, but doing nothing doesn't fix things. Having all the low paying workers commute 2 hours to work every day to make frappes and burgers for the rich locals is not a viable option.
