Eugene is right, IMO.

If a disaster strikes and you have to get home 20-30 miles on foot, you sure don't want to be the rich-guy standout. You want to blend in with all the other people trying to get home.

If the S really HTF and you do need to bug out, I would say the same concept applies: the low profile. If you're well-off, have money and goods, you want to look like everyone else, just like a homicidal maniac.
