I agree that guns are one of the few technologies that hold their value and function over the generations, but my point was more that oftentimes they're not the best investment, like Mackay mentioned. For instance, if a guy had taken that same $135 in 1963 and put it in the stock market, then reinvested the interest, using a historical investment calculator following the Dow (and not counting dividends, because the calculator I used isn't that advanced), that $135 would be worth $5,416 in 2020. Even factoring in taxes that's a nice return. Of course a person could've blown all that money on a company that went under, but then again someone could steal the gun or a house could burn down with the gun inside over the course of all those years.
