Are scissors which can't cut a sign of the failure of capitalism?

My parents owned two sets of Singer scissors, which they had bought when they got married, and still possess (and use) 42 years later. They’ve been sharpened a few times and the bolts need to be tightened, but otherwise they’re still good as new after uncountable numbers of haircuts and newspaper clippings.

A few years ago, I wanted to buy scissors. I couldn’t find anywhere that still sold Singer scissors, so I figured I’d buy a cheap pair of scissors at the dollar store. And thus began my quest. For something on the order of two years I bought pair after pair of scissors, none of which worked properly. They’d fall apart after a few uses, or the plastic handles would break, or they were too dull (or the blades too poorly aligned) to actually cut anything. Every time I went to a department store or a dollar store or a bargain store, I’d buy a pair of scissors. I probably went through 25 to 30 pairs of scissors, trying to find ONE which would actually cut stuff.

One set of scissors in particular were astounding. I paid $1 for them at a dollar store. I got them home and discovered that they had the consistency of tin foil. I could bend them like pipe cleaners with two fingers. In fact, the force of trying to cut something caused them to warp. There is absolutely no way a person could ever cut anything with them. It’s as if they set out to make something which looked like scissors while they were under plastic, but were otherwise intended just for display. I began thinking about them, and the more thinking I did, the more astounded I became. Somewhere in China, there is a factory which makes these scissors. Dozens, perhaps hundreds of people labour long, hard hours to take metal for which miners have broken their backs shoveling megatonnes of rock and transform it into something which is utterly and totally useless. I then realized that in this scissor factory, they must have an office. And in this office, they must have scissors. Which means someone had to go somewhere else to buy scissors for the scissor factory.

Leaving entirely aside the issue of morality and the theft of other people’s labour, does this not seem to indicate that capitalism has failed even on its own terms? That capitalism has proven itself utterly incapable of doing even what little good it was supposedly created to do?
