Survivorship bias. The cheap stuff doesn't last. "Take from the dresser of deal, Lacking the three glass knobs, that sheet..." - Wallace Stevens, 1922. "Deal" being cheap pine or other soft heartwood (in the poem he is trying to evoke a scene of poverty and maybe a bit of gaudiness). Not that buying old can't be an excellent strategy, it having survived either a long life, or perhaps it was just never used in which case all bets are off.
