We need wars to kill off the peasant stock and to protect my stuff from Viking marauders or perhaps the Canadians. I see a US/Canadian war on the horizon. Without hunger, people thrive and multiply. We cannot have that. If there is no more sickness, then the world population grows and we need even more wars. A viscous circle.
What we really need are more banjo players.
Actually, under my wishes, everyone would get a set number of years, live them and die painlessly. If we're going to pretend to have wishes, I'm not going to limit my imagination to tiresome realities.
