I can't contribute to the fun at the bar every night and I'm so broke conversations at work. So sad.
Pretend you're broke because you max your 401k contributions so your take home pay is low! =P
At my school, full time staff and faculty have access to a 401a (defined pension thingy with mandatory 6% pre tax contributions), 403b, and 457b. The contribution limits for a 403b and a 457b are $18,000 EACH. You can max out both of them simultaneously.
So a single person at my school earning $80k, significantly more than the median household
income in this country, could have a AGI of just 39200. After federal, state, and FICA taxes, and all those retirement contributions, the take home pay is whittled down to just $2279 a month or $27344 a year. And of course, assuming that this person is has no debts and is Mustachian, he would try to max out a Roth IRA as well.
I'm pretty sure that there would be a significant number of Americans that would claim they're broke at $2279/month of take home pay. The median household income of roughly 50,000 would result in a take home pay of $40572 or $3381, assuming this household is two adults in my state, and no tax credits or deductions (other than the standard deduction of course). That's quite a bit more take home pay than the example above (though admittedly, I'm implicitly comparing a household's expenses to a single person's expenses. But not all expenses scale linearly with more people - the most prominent example being housing).
