At the same time tuition has been soaring, technology-driven product improvements have made things not only better, but cheaper. Take Apple's (nasdaq: AAPL - news - people ) iPod, which lets today's teenagers download any song for 99 cents--one-quarter of the price (in constant dollars) that kids in 1975 paid for a 45 rpm vinyl record. And that's without factoring in the huge quality improvements that have removed the snap, crackle and pop noise featured as regular background fare on vinyl records.
Those were the days when I was buying 45's. Well, maybe a few years before that...
75% less! You can get music through iTunes "for a song".
