I tried to looking for statistics. An FBI report says that the average amount from a single bank robbery between 1996 and 2000 was less than $8,000.
The FBI's report for 2006 reports 7,272 robberies, burglaries, and larcenies. Only 6,674 (92%) were successful at making off with any loot, totalling about $70 million cash. That comes to a $10,500 average. (Robbing an armored carrier was more profitable, with 37 incidents, an 84% success rate, and $3.8 million in cash stolen, or about $100,000 per successful robbery.)
I can't find what the distribution looks like. Still, the numbers make it seem unlikely that bank robber will be able to afford "condos with oceanfront views". The average makes sense when you consider that an individual teller is likely to have only a few thousand dollars at most in their cash drawer, and in many cases less.
