I'm sorry, but 1st you said that $200K is a reasonable estimate for med school cost when I know my state school alone would put me over $300K (the estimated cost is $325K, but I know I could pull that down by living more cheaply). Then you said that working can pull the cost down to $100-120K. It's hard to work in med school, but making $80K-100K after tax, I would say is impossible. That's how much I would make after taxes in 4 years of working full-time.It's unrealistic for those who want a life duh... I think I made my disclaimer of "having no life" already.
I already doubled my current spending from 12k to 24 k... That's pretty leanient as is. I'm sure in the 24k allowance (which again is just my current expenses... Doubled. ) it will cover a cell phone - (get those pay as you go, I personally rarely talk - mostly text; and there's wifi almost everywhere), insurance (usually your employer covers the majority of it), utilities is included in my 600$/month rent (yeah it will change a lot if you end up in Boston or something). And yes, i lived as a professional before med school so yeah it's hard but it's do-able.
By those numbers - which yes - are simplified, you can pay if off in 2 years; but I said "5 years"... Which means an extra 3 years to pay it off should you decide not to live like a homeless person (3 years is another extra 150-300k that could've gone to tuition debt).
Now if you were really gun-hoe about this all - you can always work during med school and cut your loans down to 100-120k total; then pay off some during residency --> 5 years post-residency = super easy to do; even with a life.
People can't do it because they want to buy a house, a car, get married, have kids, etc - Which is all reasonable. If they want to take 30 years to repay it at 10-15% of their salary and allow interest to add on in exchange for living "happier" - that's fine. Nothing wrong with choosing a quality life. Get that newest car/phone/whatever other toys you want - I just don't want to hear those people complaining about how long it takes to pay off their debt. You made your decision - don't complain. And vice versa - I'm not going to be complaining when I pay the majority of my income towards my debt.
The things you are saying are possible but you are underestimating every number by a large amount and then overestimating how much you can make by working in school. And this is coming from someone who is going to try to live on $12K/yr during school (only possible because of medicaid, which you won't have in residency or as an attending), so I'm no crazy spender
