It's trivially true. Garbage men could pick up the trash 5x as often. Individual people could come cook for everyone. Parks could be maintained 10x as much. Trash collectors could clean up the streets all the time. More people could help the IRS catch crooks. etc. All of those things happen but 5x more people could do those jobs as well, but that would make them unprofitable to shareholders i.e. not worth paying someone minimum wage to do it. So this system doesn't get people to do that work.
