When the economy crashes it's great if you are rich. You can buy companies and stock. You don't have to pay as much for labor because workers are desperate.
Granted this is a very short term thing. In the long run, it is perhaps not so good that the pie is no longer growing in size... even if you happen to get to eat more of it. (Or not eat, no one can eat *that* much. No one can wisely spend that much money.)
Climate change has some similar features.
