“Bert Collins, an Atlanta commercial real-estate manager, recently bought two AR-15 rifles for about $1,600 each. He’s keeping one in its box, untouched, with the hope of selling it at a profit should Congress re-enact the law, which expired in 2004. “It’s certainly a better investment than my 401(k) has performed,” Mr. Collins said.

Perhaps we are witnessing the nascent beginnings of the great hollowpoint bubble of 2011. You have to respect creativity, but no investment is ever perfect. You don’t have to hide your Betterment statements from your kids. On the other hand, if the end of days is upon us, and dozens of superfast, aggressive zombies are clawing at your door, your Betterment account will not be of much help, we concede. So, we leave it up to you, the educated consumer, to decide. Just.. don’t point that investment at us, okay?
