Making it illegal for someone to take a job that pays less than $ 15 an hour doesn't affect graduates from elite colleges. Indeed, such a requirement does not likely effect anyone with average or above skills.
Outlawing jobs for people with low skills simply makes certain that millions of poor people will have no job at all and no way to gain the skills necessary to compete for a job.
Most folks learn skills on the job. Those lacking wealth and college degrees usually have only one way of learning skills -- working for next to nothing while developing the skills necessary to move up the ladder.
That ladder has now been sawed off by liberal elites and those who know no economics.
The poor and lowly skilled are the main victims of laws that cynically forbids them access to the work force.
