In Aus, investing 9.5% is mandatory (superannuation), with a few exceptions like self employed people who may have a way out of it. It isn't enough, obviously, but it's a start.
At 34, that's pretty much all I've saved - long degree, big student debt by Aussie standards, a baby, and the really big factor, paying off a mortgage. So my savings so far are about 75% of my current salary, unless you count the equity in my house, which would equate to about 5 times my salary. If you do things the "normal" way, and buy a house with a mortgage (and the median house price here is currently 11 times the median household income) then you aren't going to save much by 35. Especially if you also do the "normal" thing of kids and time off work.
