What's so hard? A "living wage" is one that enables you to pay all your expenses - food, rent, heat, transportation, and the rest.
Now was that so hard?
The only odd thing attached to other people's definitions, is that somehow some of the sillier leftists expect EVERY job to pay that much.
That's like expecting every man to be at least 6 feet tall or taller. It isn't so, and only a fool would expect it to be.
The expectation of a living wage is reasonable and possible. Your analogy is not only flawed, there's a bit of "poison" in that well.
If you use legislation to force the minimum wage to be, say, $8/hr, then all that does is eliminate all jobs that are worth less than that.
There are no jobs worth less than a living wage. Everyone who works should be able to pay their bills.
When was the last time you pulled into a gas station and had three guys come out to wash your windshield, check the oil and water, and put air in the tires?
Fifty years ago that was common at nearly every gas station. The people doing it were mostly teenagers, working their first job for pocket money, experience in doing what a boss told them, and a good recommendation from their boss for when they moved up to a better-paying job. Then the minimum wage started rising, and all those gas station windshield washers lost their jobs, except at the stations that maintained a separate "full service" island... where the gas cost more. And before long, those jobs went away too.
The first self-service gas station was opened in 1947:
1. Unemployment was 3.8% in 1947*, when the minimum wage was $0.40 an hour.**
2. Unemployment was 3.3% in 1951*, but the minimum wage was $0.75 an hour.**
Unemployment surged in 1948, but the economy had not only recovered 4 years later, unemployment was actually DOWN from before the increase in the minimum wage.
And all the while the liberal do-gooders kept crowing that they were helping the little guy... while carefully ignoring all the guys who lost their jobs as a result.
Obviously, we were helping both the little guy and the country (by lowering the unemployment rate).
I know it's hard to grasp how raising the minimum wage lowers unemployment in the long run, so here is my explanation.
Raising the minimum wage does translate into a temporary rise in unemployment, but the rise is actually very small. This is because all companies hire only as many people as they need. There just aren't that many expendable employees.
When you raise the minimum wage, a few people may lose their jobs, but the hundreds of remaining workers who got a raise spend the extra money. This stimulates the economy by--guess what--creating jobs, which lowers the unemployment rate again.
