So here you are, a clerk or some other lower on the totem pole individual who is now making $70k. You buy a house, maybe a used car, or the reverse, either way, you increase you expenses because you can. Even frugal people would do it, it's human nature.
So now it's a few years later. The company goes under, you get laid off and you go around looking for a job that pays $70k for doing what you were doing.
None to be had.
Compensation has been commensurate to your skills for hundreds of years. It may suck for the unskilled, but that's what works. For the employer and the employee. You increase your skills, you increase your pay. Do more, get paid more. When everyone makes the same or nearly the same for vastly different levels of skill and effort, then you are headed for trouble in the long term. Just look up the Jamestown Colony and how it worked out for them.
