There are some things that are more than uncomfortable, they are almost unbearable.
One of those things is poverty. They say if all you have ever known is poverty it isn't so bad because you don't know any better. I always think that people who say that have never been poor. Since from time immemorial there has always been someone who has it better and if not there is always the iron clad law of "The Grass is always greener in someone else's pasture."
When Glug the caveman dragged himself back to his little efficiency cave and tried to feed his wife and kids with the little rabbit he was able to kill and his neighbor Gork in his sprawling Mammoth Cave compound next door feasted his family and the local witch doctor on prime rib of mastodon, you can bet Glug knew the difference even though he had never experienced the difference.
