Another way that raises of minimum wages create more poor (keep in mind that a minimum wage job to begin with wasnt designed to support a family)
Example:
Joe with a new wife and child makes 17 an hour, has worked 8 years as a skilled laborer and earned his wage increases.
All of a sudden his neighbors teenage son is making 15 an hour at mcdonalds.
Inflation and the wage increase to the minimum wage - has caused goods and services to increase 3 fold.
There's a problem with that thinking. Comparing the historical inflation (
http://www.usinflationcalculator.com/inflation/historical-inflation-rates/) against the times when we've raised the minimum wages, you can only correlate inflation increases to wage hikes about eight out of twenty times. Many of the other times, wage increases coincide with notable drops in inflation that seem largely undisturbed.
Don't make me make another chart, Angel.
So basically Joe, has now suffered a loss in pay (since bottom wages have come up to nearly his earned pay) and goods and services have increased also- so his buying power with his wages has decreased along with his pay.
So, Joe is making well above minimum wage after many years of earning his raises. And he is earning a pre-tax gross wage the equivalent of $35,360. That's pretty meager, really. And in a place like Seattle, it would be tough to make it by on that. Housing alone for a family of four in Seattle would probably approach or exceed $1500/month if you assume that the kids would share a bedroom, which is around two-thirds of Joe's pre-tax wages. Bottom line, he's not even making the rent, even after years of earning his pay. You can bet that he's either going deep into debt to make that work, or he's collecting some sort of government assistance, or both.
What if, instead of making the paltry minimum of $9.32 that currently applies to Seattle, he started at something more like that $15. He would have likely been single at the time, or perhaps dating a young woman who would also likely have been working. By the time Joe reached the point in his career where he was supporting a family as you described, assuming wage increases in proportion to what he received in your scenario, around 82%, wage increases would have taken him to $27.36/hour, or a respectable $1,094.42/week at 40 hours, or $56,909.87 gross wages annually. If he's prudent and careful, he can afford to live in Seattle.
So now Joe has moved into the category of impoverished.
Is that the goal? To create MORE poor?
Ultimately, we've been failing the workers of this country for many years. We have allowed exploitation of the poor, and even the middle class, and the only way to fix it is to change things. If we follow your logic, not just Joe, but all subsequent generations will be stuck in a trap of perpetually low wages, with no way out. Making the minimum wage a living wage is a modest step on that path, and the sooner we take it, the fewer painful adjustments we'll have to make in the interim.
And to be very clear, it is only a first step. The minimum wage doesn't move major economic indicators much in any direction, because it mostly functions at the edge of the economy. I would like to see mandatory leave minimums for all workers, including part-time workers, including sick leave and enough vacation time for a few vacations a year. I don't believe that those things are extravagant, and they are things that other countries have been able to do without wrecking their economies. And I think that would help the middle class a lot more than hiking the minimum wage.
