I will go from what I had in undergrad (very different then now, with 7 years out and an older husband with a good career.)
Luxuries: a pet turtle, tomato plants, a microwave, hotplate, and mini fridge, a 'free' dorm room in exchange for being an RA, the opportunity to do research, excellent professors, a 1980 (note I was born in 1979) chevy standard with 200k+ miles on it (odometer stopped turning at 200k), a desk in the bio wing for research/ta/tutor work, ethernet, a 386 PC, gown for graduation (gift from research advisor), microwave air popper for popcorn
Non-luxuries-tap water as only beverage ever, working 40-50+ hours per week with classes (80+ without), not including RA tasks, working hard labor positions for long hours to make money, waking up at 4am to start work, and going to bed after the late shift (1am) most days/nights of college, beans and rice out of warehouse bags for 95% of meals, no phone (not cell, not dorm), walked everywhere within 3 miles of any part of campus (car was only for driving to the research centers 30minutes, 1 hours, and 2 hours away), no visits home, family couldn't/wouldn't afford to come to graduation,
Hmmm.... maybe there is a good reason I worry about how much vet school will cost and my future debt:income ratio! I already know what it is like to pay a large chunk of monthly income in student loans.... and what happens when you get sick, in a car wreck, get hit by a natural disaster, etc
