Minimum wage jobs are not meant to support a family on, even though some people are trying to do just that. Then they scream for higher minimum wages which can only mean even fewer jobs.
But, wouldn't the reverse hold equally true?
If for instance, we reduce minimum wages to increase the amount of jobs, what good will that do? If we reduce minimum wage, or get rid of it, and people 'are not meant to support a family on' minimum wage jobs, then reducing payment of these jobs that people are currently relying on will force these people back into the job market to look for more jobs to offset the lessened amount of money they are receiving per paycheck.
If we measure the amount of jobs as equal to the amount of money saved, (since this model makes no sense otherwise) then the job market should, theoretically, see little to no change in the ratio between people with jobs and people without.
Of course, if that does not end up being the case, and still assuming that amount of money saved = jobs created, then that would mean that more people have jobs that you can't support a family on, resulting in a higher number of people below the poverty line.
