I feel for you, that's a messed up system.

I can only tell you what I might try. I'm not working either and I've been fighting health problems for a few years now. Someday I'll be strong enough to get back in the swing, and all the folks here helped show me that electronics is where I'd be happiest. I might wind up fighting the same sort of issues here in the US (I'm 31 now), so I've given it some thought.
I'd leverage my spare time against the system, as it's my primary asset in such a situation. My advice would be to speak with as many people as you can to try to find a way through. Speak with and write to education officials, government officials, teachers, students, student organizations, industry organizations, print and television media, elder advocacy groups (even though you're not there yet it's a material issue to them), anyone you can get your hands on. Make as huge a stink as you can, and use the facts against them.
The system as it stands seems to discriminate against adults (anyone over 20), so ask them to prove it's not doing so! They should be able to show some sort of support for those who are intelligent and willing students and don't happen to be fresh out of secondary school. If there's money for education out there it's an economic issue to ignore the elder three quarters of the population. It'd be a horrible waste of resources!
Above all, stay strong. Keep looking for a way into industry with the qualifications you already have. I know it's hard when you'd rather be doing electronics than political activism. I've been through a small version of this with a friend of mine who couldn't get work here due to a juvenile conviction. It didn't turn into an epic battle, we actually found him a job with a railroad track test company and he's been there six years now, happy as a clam.
You've got us here too for support and ideas.

Hope that helps, sorry if I got a bit preachy.
