It's one thing to profit obscenely. Sometimes you get lucky on an investment. It's another to see that a war is going on, be a congressman, and to invest in the sector that the government pays (perhaps by necessity, which is not to discount the selection process shenanigans) and put yourself in a position to have a personal interest beyond the country's for continuing the war.
Because I hold myself to a high standard of integrity, I tend to think US Reps and Senators do as well.
