The argument isn't directly about what you're talking about in this thread, but it's taking the same mindset to a logical extreme. It really isn't all that different, but you already know that.
Haha, yeah. I definitely agree we need to mind the way nature reacts to what we do. We need to find other sources of energy (possibly something other than fusion reactions! ), be better about recycling our waste, etc. However, I also believe that people need to take a break. The latter point has little to do with the former, but I think it's important everyone "treats" themself to a break once in a while.
You're certainly right. Everybody deserves a break. (Have a break, have a Kit Kat! They paid me to say that...).
But is it right to pay many people a low (often, I hear, lower-than-legal) wage to do work, taking it away from other people, is the right way to "treat yourself"? If everybody started hiring workers like that, the world would be shittier place. And that's the problem.
This reminds me of that South Park where the future-people came and started taking jobs, working for pennies. Stan's dad (Randy) said it was ok, and pretty much what you said. Then one of them took his job as a geologist for pennies. He was pissed off. I think it ended up as a gay orgy or something...
