If worker unions were required by law then I would agree. The issue is that companies will corner the job market to suppress wages. The government applies some pressure the opposite way via minimum wages to help force progress. Self checkouts and various other automated processes don’t occur without some kind of selection pressure.
Think of minimum wages as forcing weaker companies out of the market.
Not to be a devil’s advocate but the little people aren’t paying taxes. The top 20% pay the taxes for the most part, the problem is the money in the first place giving too small of a group of people too much say in how everyone lives.
