Only so long as our outrageous income disparity continues to exist.
If the wealth of this nation were brought down to the middle class and distributed more appropriately among employees, you could afford to pay them more without having to raise prices on goods.
That being said, I'm not a huge fan of just raising the minimum wage. It only benefits the economy if those at the top allowed their wealth to trickle down to pay the difference, but common sense and recent history both indicate that won't happen. And there's no practical way to force that without radical economic changes that would never get political support. Not until there's an uprising, anyway. That seems to be the inedible conclusion when this kind of disparity exists long enough, and the majority are driven far enough into desperation.
Let's take this to a theoretical, but impractical, extreme.
We double the min. wage.
Now, for some stupid ass reason, real wages don't increase (they would.) in anyway.
So, more money but no more supply? Inflation.
We doubled, so that's 100% Inflation.
In order to keep up with this inflation, the average household now earns roughly 55% more than the year before (in nominal terms, i.e. a drop of -45%)
Now; Let's say Mr. Jones and family make up the average household.
Mr. Jones has 1.3 kids and a wife, they take home 50k a year. (~75k/yr after inflation)
They now live in a four bedroom house @ 300,000 dollars a year.
Let's say their mortgage in gov't insured, and they pay the maximum of 34% of their gross monthly income (pre-tax) in the mortgage of 1,416 PITI.
Now, the mortgage rate on the 300k loan is 3-5% (in nominal terms, as practically all private debt is written). Meaning that, the amount they owe won't change NO MATTER HOW MUCH inflation OCCURS.
So now, paying 1,416 a month only equates to 23% of gross monthly income. (Now apply this to all debts, like a car payment or even past credit card debts)
Do you see what raising the Price Level, De-Valuing the Currency does to
debt. Do you now grasp, IN THE MOST UNREALISTIC AND WORST CASE SCENARIO, how raising the minimum wage in what we ALL consider to be a DEBT - Fuelled economy would be good for the AVERAGE American?
Now, there's some macro issues like perceived involatilly and possible loss of reserve currency status further de-valuing and increasing base interest rates for dollar-denominated debts. But this is an extremely simple scenario.
I too, am not pro "Minimum wage". I am pro collective bargaining, I'm pro equality, I'm pro labour, I'm pro begging wages to corporate payroll structure. Hell, I'm even pro net "productivity" bonuses and an entire industry based on that alone.
I just think that a minimum wage hike, federally, is the only politically realistic way to go about it.
