That's the point of the thread in a nutshell.
For an ordinary wage earner, spending $700 is not financially smart. It's nice to do once in a while of course, but if you are on a path to wealth, it's the wrong expenditure....
Unless of course it's accommodation in the pursuit of earning investing/earned income and can be claimed as a tax deduction somehow.
But even then; you still don't need to spend that much just because you can - spend a bit less and save some coin towards the next parcel of shares/business/IP, etc.
It's one of those financial decisions similar to buying the brand new car, or buying the ex-demo/12 month old version and saving several thousands/tens of thousands - we've all bought the brand new car at some stage - but now I know better - you don't buy the brand new car; you buy the exact same car a few thousand KM's old, or a year old...still basically brand new, but loads of money saved.
