Getting a degree and then working in the air conditioning isn't the only way to provide for your family's well being.
I think people sadly ignore the fact that there are many ways in which to provide for your family.
My old man starting his own house painting business. It was back breaking work but we managed and eventually moved up..... not that we were ever RICH... but my father was too proud to go on social programs.... not that they were as available as they are now anyways.
All things MORE government can't help.Look at teen stats for driving, STDs, teen pregnancy rates, and other such things, they will show just how "responsible" most teens are in our current society.
The only thing that can help this is good parenting.
What you are basically advocating if I am getting this right is because modern parenting has been a general FAIL to teach responsibility to teenagers, that we should treat them like babies longer because it will take them longer to figure it out on their own.
You are "subsidizing" parental apathy.
on the other hand, if a 12 year old commits a crime and a 30 year old commits the same crime, there absolutely should be a difference ... if we're going to treat them the same, then 12 year olds should be able to drive, serve in the military, buy cigarettes and liquor, etc. .... agreed?
