Rome was prosperous and decadent. Rome was full of loungers. Rome also eventually fell, but at least the loungers were well rested! And they lived happily ever after.
Who do you think really suffered when Rome fell? Here's a hint: not the people with loungers. The people who suffered were the rank-and-file who had to deal with a bunch of angry barbarians knocking down gates. The rank-and-file were unlounged, and as such, very tired. They had no where to go and nothing to do. But the lounging class, ah! The lounging class were healthy and happy and had lots of contacts around the world (due to their shared interest in lounging) and they all escaped to found lounging dynasties that continue even to this day.
The moral of the story: be a lounger. It'll pay off when society collapses.
