If you are planning to go uni then go live in scotland. Free uni. If you finished it, show your wage under 21k and you will be safe.
So if you can find a way to beat the system i say do it...hands down!!!!!
Today, yes the learning thing IS A SHAM! They screw so many people out of their money ots crazy...then when they graduate, many cant get a job. Go here to see how it is in the states, its a jpg so click it to expand it. Seems like a real money maker.
As far as getting out of loans, atleast here in the US, there is nothing you can do that i can think of except for leaving the country and never coming back.
You are essentially saying don't pay the loans he agreed to pay.
I can see you weren't raised by me; if my children sign a contract they honor it.
