I honestly don't understand the anger being directed at this kid.

Don't read his posts.
I can say from personal experience the two monthly average mongering amounts being questioned on this thread are absolutely not unrealistic.
I've had a similar mongering budget for, well, decades.
Not saying it is wise or advisable, but it is certainly doable, especially if you 1) have a decent job and 2) don't splurge on other things.
