I'm middle class ^_^ I farm and mine enough to cover my expenses and have a nice little savings
Being upper-class on Graal 2001 is not worth the time, 80% of the hats do not interest me. And unless you want to buy a lot of hats, having all that money is useless
Graal seems to work like real life... the top 10% own about 75% (or maybe more) of the total money
Stefan posted these stats once... I wonder if he will post some updated ones.
