We get what you guys are talking about with the numbers too. But they're big for a reason...
"probably a bit of import/export and commodities investing,"
What? You mean like... stuff imported from china?
"real estate, and smalltime moneylending (he is "welcome" at the London Stock Exchange and has a warehouse, probably for loan collateral and wholesale goods)."
Access to wealthy people willing to invest... and warehouse space to store.. I don't know... Imported Opium?
