Unless there is some way to possibly identify the person who lost it, it's just found money. You can call the police and report it, but it'll extremely unlikely that it'll be found by the person who lost it, or even reported.
A "huge roll of bills" is usually associated with crime, so I'd just thank your lucky stars and spend it like it's yours.
If it was in a wallet or purse, I'd most definitely try to find the owner, but simply cash on the ground? No.
I found some money underwater, snagged on a reef in Thailand. I didn't report it, and spent it on beer. Was that ethically and legally sound of me?
Finding cash on the ground is not stealing. In order to be charged with theft, intent has to be proven. You cannot do that with found money.

Actually, you can steal from thieves and no, every rich person did not get rich by exploiting others. Poor generalization. You sure hate people better off than yourself, don't you? Sheesh!
