It's not rocket science. Let's ignore housing for a moment.
The only other expenses that are reasonable to finance are education, medical, and possibly a car. If your degree will boost your long-term earning potential, then it's rational to take out as much in loans as the extra earnings (minus lost wages while in school) over perhaps a 5-7 year timeframe (about as often as people switch careers). For example, assume a diploma nets you $25,000 a year and there is no inflation. Over 10 years (4 for BS and 6 for work), a HS grad earns $250,000. Let's say the college grad has picked a profession where $50,000 salaries are common, they work 6 years for $300,000. We can see that over a reasonable time horizon, the college grad makes $50,000 more than the HS grad, so he should take out no more than $50,000 (including interest) in student loans.
Medical loans are as much a moral decision as a financial one, so I won't dare to offer suggestions here. Now, about cars. If you can't pay cash, you do not deserve a new car. In our society, you probably need a car to get to/from work and social obligations, so go ahead and buy one. But unless you are paying cash, you should get the absolute cheapest car that meets your needs. This is going to be something like a used Hyundai sedan, which probably goes for less than $4000 with less than 100,000 miles (required for most loans). Such a car should cost less than $150 a month over 3 years (not 5 or 7!!!)
Housing, of course you can rent if you don't want any debt. It's worked out well for people for literally thousands of years.
