I'm not jealous of a complete PS2 collection, at least 80-90% of the games are shit and they're all sealed so they won't be played with anyway. I just know I wouldn't want that much crap taking up space, it would drive me nuts.
I think most collectors who are angry aren't jealous of the collection, they're more annoyed with how someone can waste so much money on stupid shit when they could have put it to better use themselves. Like if someone was struggling to find a way to pay for needed home repairs or schooling and then reads about some random rich guy who bought 10,000 Hot Pockets to throw at cars off the highway as a prank. That type of stuff is annoying. That's the mindset I think most people have anyway.
