The best paying jobs are increasingly removed from any real form of value creation. Western Markets value deception, financialization, and asset inflation far more than actual labor, accurate accounting, and efficient administration. The professional test-writer makes more than the teacher. The real estate agent makes more than the construction worker. The insurance actuary makes more than the physician. The salesman makes more than the factory worker.
Follow this business logic to its ultimate conclusion and everything becomes an MLM.
There are those in society who enjoy that others are poor. They enjoy it because it means by contrast they are rich and successful, even if they are nothing compared to the 1%
The idea that people working in 'mundane' jobs could afford to live and enjoy themselves is an affront to their dignity.
There's a social ladder. Everyone above is God to be worshipped, and everyone below them is trash who deserves to get pushed down.
They also have a direct material interest, because higher wages for workers would result in capitalists raising prices for everyone, so they would themselves become poorer, so they support the existence of the underclass to protect their own relative wellbeing.
Or how about "until capitalism is fixed for everyone, here's a way to better your own situation." And as a happy little bonus, if supply and demand is accurate to the workforce, it will create a bit of pressure towards better pay for the people who do the old job.
