As I recall, MB did an internship with the company whose web site is at the link below. The surnames make me wonder if there is a familial connection between the executives of this company and both MB and LS' female friend BW. http://www.wallachbeth.com/index.php No proven connection, however.
MB's father is co-owner of that company. The last names of his partner is not that common. While I know it's not her father it could be an uncle or a cousin of the father, not 100% sure on relation. MB does have money but not in the likes of DB and JR. But his father is a commodities trader and owns a brokerage house with an address on Wall St. I wouldn't say he's Billy Ray Valentine from Trading Places. They are doing far better than I am in the cash flow dept. difference is I have morals and a conscious.
