I know how much you libs hate it but let's do some math.
Example.
A food truck in Seattle that is open 9-5 weekdays only (for simplification but results for more hours are easily extrapolated from this example)
Let's say the owner has 3 full time 9-5 employees 5 days a week and pays them all $9 an hour
His payroll including the employer FICA contributions is 60,372 Actual payroll includes other crap but we'll leave that out
The truck sells 100 sandwiches a day at 7.50 each so his annual sales are 195000
Let's assume a food cost of a conservative 30% of gross revenue so that 58,000 a year
That leaves 76,628 before truck payments, equipment, maintenance, consumables,insurance, fuel, permits, worker's comp, etc
The truck owner will probably make about 40K a year on his truck if he's lucky
He now has to pay everyone 15 an hour therefore his payroll is now 100,620
if we assume all his costs stay the same (which they won't because all his suppliers will have to cover the costs of their higher payrolls as well) he now is in the hole to the tune of 248 a year and has made zero income
Factor in all the other costs that will rise as everyone else has to cover their increases in payroll and our truck owner is even deeper in the hole.
So what does he do? Raise all his prices? Fire a guy or two? Both?
Sell the truck and get out with the profit he can?
I do not see how you people think raising the MW drastically will make everyone richer
