Oh yes I didn't respond to the student part.
When I was in uni, I worked a few casual jobs - but probably didn't really do more than 30 hours a week. I can't remember them all but some notable ones included tutoring (I started out at $30/hour but progressively went to $100/hour and there was a big market for it, HUGE in fact), working for a private entrepreneur on designing a software (I was writing the actual content while a programmer was writing the code, if that made sense), I ran a tutoring school at some point. I got an internship in my second last year at uni at an annual rate of $90k I think (can't remember now), although being an internship obviously only did two months there (that internship involved long hours). My first year out of uni was in financial services, and paid around $150-160k, but yes that had the hours with it. Although if I had my time again, I would've known where to go to get the $150-160k in my first year without working more than 50 hours a week.
And yes, certainly $100k is quite standard these days in many professional careers I've come across for late 20s, and I would agree $200k would have to be the new $100k for many Gen Ys. It's like 10m dollars is the new definition of a millionaire to you guys, surely. $10m many years ago would let you buy a street, these days you'd get 1 or 2 properties on some of the same streets only, and in some, none.
But really, the point of the earlier post is that, yes, there are MANY Gen Ys on $100k who are living pay cheque to pay cheque. No amount of education/high income can teach you to be financially prudent was really my point. In fact I once had a guy earning maybe around $500-800k pa (depending on the year) tell me, if he lost his job, he'd be ****ed and lose his house and car etc. Another example of living beyond your means.
So to answer a question commonly asked. Is housing that unaffordable for Gen Y? I guess it is, but it will more likely than not be because of your own doing.
