I'm rich, but not that rich. I carry my wallet in my pocket. It usually only contains my driver license, debit card and donor card. (I have donated my carcass to science after I croak.) That leaves my hands free to carry sacks of cement and cinder blocks and stuff like that.
Not rich .. comfortable. I don't carry much cash ... and my wallet is in my purse. We mainly use our debit card and if we do use credit cards ... we pay them off every month and aren't charged any interest, but I digress. :)
