I didn't bother with the graphs. Not really in the mood to sort all that shit out right now.
16 million people in the US make minimum wage. only 20% of those 16 million are under 20.
What do you think the minimum wage should be
Doesn't matter. We don't need workers any more. All the high paying manufacturing jobs have been gone for a while. All the high paying white collar jobs are disappearing quickly.
Self driving cars are less than 20 years away. After that we won't need anyone who gets paid to drive, including truckers, bus drivers, taxi drivers, delivery people.
So either in the not too distant future, the vast majority of the world will be in abject poverty (and that tends to cause revolutions), or we'll have guaranteed income. Everyone will be given a living wage for doing very little or nothing at all.
