I notice the people who get upset about this stuff, it's not because they are against a livable wage. It's an ego thing.
It's also a convenience thing, cheap an easy is more important than human beings.
They feel they earned the right to be in a class above these workers.
If these low skill workers close the gap on their wages, then in their mind, it lessens their achievement.
I'm not as well off if you're doing better. They base how well they are doing by how big the gap is between them and others, not by if they are happy or comfortable.
It's like when people say "I'm an EMT and make 15$ an hour why should fast food workers make the same as me?"
Notice how their thought was why do fast food workers make the same as me. Not why don't I make more than fast food workers. The irony is this is the same argument the fast food workers are making. They just don't realize they are also being fukked.
People don't feel good about themselves unless they know others are doing worse, it's a sad fact.
