I don't agree with this comment at all. Until recently I worked at a top tier law firm and a lunchtime conversation of property ownership came up when one junior lawyer was lamenting that he and his partner couldn't afford to purchase a property. At the time I was earning half what he was earning, and around 1/4 that of some of the others in the room, yet my net wealth and gross ownership value was many times that of anyone else there. Each of them earn over 200K yet they have lifestyles that come with the job - having to rent close to work as they are always at the office, buying expensive work clothes, lots of eating out at fancy restaurants, expensive holidays away to locations where blackberrys don't work. Their attitude? I work damn hard for my money, why not enjoy my life rather than create a lifestyle for the future.
A few years back I had a conversation with a partner of the firm I was leaving. He said I was "lucky" I could leave my job rather than being chained to it. He earned over 1mil per year but had to live in the Mosman mansion, have the kids in private school, stud fees for the daughter's pony etc etc etc. He said he can't afford to buy an investment property.
So what's to say that those 1mil doctors will be wealthy once they retire?
