If I understand correctly, pg didn't quit YC completely. He only resigned as YC president and now is a normal partner. If he was making millions, now he is probably making only 3/4 millions, not in the unemployment row.

He also resigned as the main HN moredator/administrator/spokeman/programer/whatever and put a few people to cover those tasks. He didn't earn money directly from that work, it was a side project that grew out of control. (I suspect he's still watching from the shadows. Hi!)
