It is simply a game of eliminating competition.
Of course, the money will be worth more when it's scarcer too.
The reality is a lot of companies, banks, and politicians have finally recognized that the US consumer class is tapped out and a significant portion of the world relies on that as a central economic engine. Even China isn't ready to fully switch away from being export-driven. To have consumers you need people with money in their pockets to spend. That means management and capital need to move back toward the historical division of profits with labor. We'll all end up better off in the long run.
California raising the minimum wage will barely impact unemployment. A few prices will rise a bit but the net effect should be positive. Some of the money will be due to multiplier effects but some will come from obsessively high corporate profits which is fine (companies are so overflowing with cash many are doing record stock buybacks for lack of a better ROI).
Companies that trying to sell you stuff don't look for an equilibrium it's not like they are saying you have to buy milk, apples, and bread so lets see how much you make to maximize profits if they are the ones that selling you milk and bread they'll charge you as much as "humanly" possible to the point of forcing you to give up on the apples.
Since you mentioned milk, let's use that. In the UK, in 1914, a pint of milk cost 1d, and the average wage was 16s 6d for a standard 58 hour working week.
That's an average wage of 198 pints of milk per week, or 3.4 pints of milk per hour.
In 2016, a pint of milk is 45p. The minimum wage is £7.20, or 16 pints of milk per hour. If you buy your milk in four-pint bottles (economies of scale not available in 1914), your wage doubles to 32 pints of milk per hour, a nearly 10-fold increase on a hundred years ago, and you're only working two-thirds of the amount of time per week, too!
Ex. Someone who would be making 9 would see 66% increase in wages but because wage earners as a whole would only be earning a little more so the increase in prices would be proportional to the overall increase not the much larger individual increase.
Suppose that wages earned only increased 6%. The individual would easily see a great increase to his standard of living despite a small bump in price.
Also note there is no reason to believe that costs of businesses that rely on minimum wage work would go through the roof. Imagine 30% of their costs are labor and 2/3 is minimum wage work. 20% of their cost then double it perhaps and their costs increase 20%.
Note we are talking about an atypical service oriented business dominated by minimum wage labor.
This means that your taco costs a few more dimes but the dude making it doesn't need food stamps and welfare on your dime.
Perhaps you made a typo, but if not, you just said something that's exactly the opposite of reality.
Do you have any data that even slightly backs up what you just wrote?
Also googling "prices increasing faster than wages"...
How? Efficiency.
Putting the pallets directly into the store saves 2 people who’d otherwise be stocking up shelves, for example.
Making shopping carts cost a deposit, which you get back upon bringing them back, ensures that you save another employee who’d otherwise work on that – instead, money-conscious families, homeless and teens do that for you.
A lot of companies can compete with Walmart at lower prices and higher wages – even in its home market.
Increases to the minimum wage have had a brutal effect on black and youth employment, for obvious reasons. It's amazing how minimum-wage advocates refuse to accept reality.
The minimum wage should be the lowest amount a person is willing to work for.
I probably benefit 15k annually. Making the crappy 14k I'm making survivable. My wife can't work due to medical issues.
Basically we don't have a rational market now and can't so the only rational way to keep companies from riding on everyone's tax dollars is to set an artificial floor.
That is literally what is happening now and there is no reason to suppose that in the absence of benefits that wages would be adjusted upward to compensate with any degree of expediency.
The people of our nations are precisely stupid enough to let the economy crash and burn as has been previously shown.
