I think it becomes shame because we recognize we've benefited from the system that has shit all over so many. Even indirectly, it's hard to think about all the ways I've benefited from - just to say one thing - all the cheap open land (places like texas, nebraska, oklahoma, OR & WA) we got after putting the natives in concentration camps and murdering most of them.
Like, I try to enjoy a national park but then realize: this was someone's home. Many peoples, in fact. We took it, put up gates, and charge people to harass the animals. And that's the places we've saved from industrial pollution and factory farming.
at one point I had a 17" (no name) and a 21" view sonic on the same desk bench, connected to a dual ppro 200mhz (tyan mobo) machine I built running windows 2000, the first os I used that supported multiple monitors. our engineer custom designed the benches out of steel square tubing and laminate wood, they were great.
