A $15 minimum raise hike is more likely to close down jobs in the mid wage category than in the low wage. A hike probably means money will move from the mid income-overall to the low income-overall because low wage produced goods were relatively under priced (not "marked to market" due to prior monopsony).
Think the 65% of McDonald's customer coming through the drive thru.
Consumers tend to purchase more of goods produced by employees at their own wage level. Ergo, when income flows overall from the mid to the low -- the low may disproportionately spend that new money among themselves. While some mid wage firms may lose business as prior sales money goes south and be forced to lay off workers.
Easy way to make the loss from mid to low as painless as possible: hybrid redistribution via tax hikes for the (really) top with matching tax cuts for the mids.
I am thinking (just to throw something out) 90% taxes on all income over $2 million dollars. Maybe 50% over $650,000 (the entry to the top 1%?).
Under the theory that people will enthusiastically work for $200 a week if that is the best their economic place and time can do: the very same people will not work for $400 a week if their era could and should be paying $800.
I'm thinking grossly underpaid Chicago retail clerk (could be $800 a week -- instead of $400 -- marked to market via collective bargaining) which I say explains why Chicago gangs now include an intolerable 100,000 out of my guesstimate 200,000 gang-age, minority males. I'm also thinking old American born taxi drivers like myself who wont work 60 grueling hours for today's $500 a week (did for $750). I'm thinking family raising adults who no longer show up for two-tier (thanks to Walmart) contract supermarket work.
Today's-time and US-place CEOs, professional athletes (who basically just retain feral animal skills), TV news anchors and movie stars earn 20 times what their 50s and 60s predecessors did -- they can certainly pay similarly high tax rates (though not from as low a starting point -- double per capita income later). They will work just as hard once they get used to the new (hybrid) redistribution regime representing the most anybody can squeeze out of their era.
