Seriously now - if you want to assess whether you can afford to buy a car in the US or UK, would you base your costs on the price of a Mercedes or a Rolls Royce? Harvard at $70k/yr costs a fair bit more than almost any other medical school in the world.

You would be better off looking at in state tuition to medical schools where you live, and also consider general costs of out of state tuition if your daughter chooses another location. For example in state tuition to the University of Washington Med School is around $13,500, out of state tuition approximately $32,000. Its difficult to generalize on costs across all medical schools, but US med school tends to be expensive, and most med students take out loans, which (hopefully) they repay in later years when they earn a good salary.

One other interesting US trend is a number of med students are older, in their 30s - they're becoming doctors later in life, after a first career doing something else. If your daughter had issues earlier in her (pre-med?) studies, it may be a sign that she's not prepared to go to med school right now. No worries - I would appreciate if my doctor came to medicine a little later in life with more maturity and a better sense of why they want to do the job, instead of slotting right into the work right out of college, not entirely sure whether its a good profession for them. Kids go into professions for the strangest reasons sometimes.
