For some people, immense wealth encourages stupid decision-making.
TEXT OF COMIC:
Actually, I think Cathy’s charmed life isn’t entirely luck.
At least, I know that one piece of good luck can lead to others. It isn’t just a series of unconnected random events that led to her having a lucky life.
If you’re born rich, for instance, that good luck can cause other lucky things: you’ll probably have a better job, be healthier, and have an easier time finding a mate. It’s not guaranteed, but your chance of a lucky life is higher than if you were born poor.
That doesn’t explain all the celebrities who have crappy lives.
At some point it stops being luck and starts being really stupid decision-making.
