^ +infinity. You get so many "...why would you want to do x degree if you could do y degree instead and get a better job, quicker?"
In my case, it's "why would you want to do a BSci at Melbourne and have no job at the end when you could get into MBBS at Monash?". After I explained the whole guaranteed entrance thing, my Mum was still iffy about it. To be fair though, getting into postgrad places after finishing a BSci is highly competitive, especially when many have only about 20 or 30 places available...
In a nicer world, we would all be able to just study what we like and not worry about work/money/etc. but in the end, that's a luxury that's really only available to high achievers. For so many kids, it's not a realistic option - it's do a course that will guarantee you a decent living at the end, or else you're screwed for life.
I think what the government needs to do is make transitions into postgrad more accessible for graduating BSci students. It's ridiculously competitive for those who don't have guaranteed entrance (ie. the vast majority of science students), many don't have any choice but to find a job for a year and reapply the next year, and if that doesn't work out for them, they're just going to end up staying in work rather than getting the postgrad qualifications the government wants them to get. I think there should be more funding, more CSP places available in postgrad areas where the nation needs more professionals, eg. maths, allied health
So yes, that's my 2 cents on what the govt should do, but they're awfully stingy with opening up new CSP places for anything, so probably not going to happen any time soon.
