That's an excellent observation, Heather. I'm in a similar position now with my daughter, whose college is costing my every dime I can afford. If she needs to go to graduate school, I won't be able to help and she will have to think about a career in terms of loan repayment.
One answer--for medical school--would be to incentivize more doctors to become general practitioners and to practice in rural or low-income areas for five or more years with a reduced or free tuition. Then they wouldn't worry about the burden of medical school. But hey, that's just me!
I hope that your daughter enjoyed Latin. If taught well, students really love it; if taught badly, well, they don't. And I'm sorry your son's school didn't teach Latin. (If they'd like to, let me know. I may know a guy...)
Thanks so much for reading and responding, my friend. I appreciate you.
