$5000 for a computer in the 90's??? I must have hung around a significantly different crowd than you did...
When I was living paycheck to paycheck in my twenties (which would have been in the early 90's), I had a rent (which included utilities and cable), car payment, car insurance and a credit card with a $1000 limit...life was alot simpler back then...I had several friends who were BBS junkies and I am pretty sure they didn't spend $5k on a their computers...they barely had enough for beer money (who knows, maybe they did spend $5k on computers and I just didn't know it)...
Truth is, there is barely any disposable income after you payoff your necessities, such as $100 cable or satellite bill, home internet, cell phone with voice/data texting, cigarettes, beer, going to see the latest movies every weekend and rolling on your 21" rims...
If you go to any site that helps you set a budget so you can save for the future, the first things to go are cable, high monthly cell phone bills, etc...but fuck that, it is someone's fault you don't have enough money....
