No, not anybody can. What if you have a family and are barely making ends meet as it is? It's very difficult to convince a wife that you'd like for the family to spend a little less so you can have a few months off next year between jobs.
Assuming a low-end IT salary, you're still bringing in 5k+/month. Minus $2000 for tax, zero for your 10 year old cheap car, $1000 for rent, and another $500 for food, that leaves $1500 for conspicuous consumption or savings.
If you've chosen to use up that excess by upgrading apartments, leasing a car, buying a flatscreen on the Visa card, etc., that's what is eating up your ability to save money.
There's no reason to be living month to month on $60k+ a year. Unless that's what you've chosen to do.
As for food, I eat far better than beans and rice, and I probably only spend about $150/month (ignoring restaurants). I'm a 100kg man who eats a lot. $500/month is easily plausible for a family which does not have large teenage children. (This of course assumes a non-working wife to prepare food from scratch, but again, if the wife works, more money to play with.)
Start thinking that way, and keep at it for a while and suddenly you'll find you're not living month-to-month anymore.
