We all have to remember & tell others this:
EVERY single penny that the minimum wage is increased is added to EVERY single union contract in the USA.
No matter how much per hour that union member is already making—a raise in the minimum wage increases their wages by the same amount.
You are correct. No minimum wage increase push has anything to do with people making minimum wage. The unions want their wage contracts (and subsequent dues) inflated and the minimum wage is the baseline. If it were up to them, these fast food workers would all become union apprentices or unemployed- not making $15 an hour!
