Index Cards

Why the hell is it so hard to find quality index cards in todays world?  When I was a kid, index cards were actually made of card stock.  Now they are barely any thicker then normal ruled paper.  It really frustrates me how cheap and crappy companies make their shit nowadays.  I have bought index cards by three companies at three different places and all of them were lighter in 90 lbs. card stock.  Barely heavier then 60 lbs. paper.  I guess this is what happens when companies use post consumer waste, the paper turns to shit.
