I can’t spoon feed this stuff to you anymore. Unions are the cause of the clogged up shipping port debacle in our country right now. Fact. Not opinion. Biden is inept in all ways and his ineptitude spreads wide, but the unions are why the docs don’t allow more working hours to take care of the boats.
Unions have their place and do give a few groups better pay. The middle class is those who work decent jobs (doctor, pilot, engineer, or anyone successful in their industry), but that nonetheless work for pay. The lower class work entry level, low skill jobs. The upper class own the things.
