Trickle up economics will work, trickle down did/does not work. Paying people a decent wage puts more money into the economy and thus would be the rising tide that truly raises all boats.

I just don't think folks who make and have plenty of money are in touch with what the lower class needs. $15 an hour might be better than current wage. But it's not going to change anything. A true wage is more like $22. This is why @AndrewYangVFA and has my vote.

Won’t the price of living go up ?

Then everything else goes up how can people get ahead. In the state of Maine it’s 11 dollars and hour and everything else went up to match it.. 3 bedroom apartments are now 1100 in a crappy part of town.. what is the right answer
