we'd all like to think that it has gotten harder because it makes us feel better and smarter, but it's not as black and white as that. physicians have always been esteemed members of society. while they may not have had to do ECs and shadowing, they likely made up for it by studying more. After all, studying was probably harder back then without internet access at their fingertips. As RokChalkJayhawk said, there is only a finite amount of time per day.
if we really wanted to answer OP's question, we would have to define what EASY really means. As in, just comparing acceptance rates or is it more ECs required, etc.
OP, as for your uncle's white males comment, he was most likely referring to the Civil Rights movement, which was more than 25 years ago.
i know AAMC keeps track of stats like acceptance rate and race but I don't know how far back.
