Your experience is your personal history. You are effectively saying everyone else has, or should have, the identical life history as you. You are but one of many millions, and your story is not everyone's story. What that DQ job was to you, and may typically have been to many, is not what the job would be to all. Nor do people today have the same employment market ahead of them that you did.
Many years ago, Sharon worked as an Occupational Work Study coordinator in the local public school. Some of the students worked part-time jobs at fast food restaurants during the school day. Part of her responsibility was to make home visits. You would not believe the horror stories she would see, and this was in Fremont, OH, a small town in an agricultural area with some small industries, not some big city housing project.
How many of those students were/are capable of repeating your life experience? But, they all grow up to become adults just like you did. No one is ever going to pay them a "high" wage. They work, but earn less than a living wage. That financial shortfall is back-filled, likely all of their lives, with charity and tax payer support such as Section 8 housing, earned income credits, and food stamps.
It may be convenient to think they should have done what you, and most of us here did, but that is a fantasy. There will always be a population segment that falls in that category. Would it not be better to pay a living wage that sets a non-welfare based example for their children? If you think they aren't going to have children because they cannot afford them, that would be another fantasy.
Personally, I would rather see those who do the work rewarded, than having the Krocs, Waltons and Gates people hold the money and later pass it out--maybe. It sounds to me like a reasonable method of encouraging and reinforcing a stronger work ethic--which you are implying is in short supply.
