Why do people throw perfectly good stuff away?

My daughter lives in low income housing—an apartment complex. (I mention this because she mentioned it in her FB post:“Ok, I’m failing to understand how you can live in LOW INCOME HOUSING and afford to throw away a 300.00 high chair. Yup that was me dragging it away from the dumpster this morning.”) This morning she took the trash out to the common dumpster and she found a perfectly good, almost new high chair just sitting by the dumpster. She said it wasn’t a WalMart chair either. It has three different positions, reclines, has cup holders on the back and some sort of food storage thing for toddlers (I have nothing to compare it to. I’ve never heard of such a thing!) She said it has to be a $300 chair. And it was just sitting by the dumpster. The dumpster is surrounded by a privacy fence, so it had to have been put there deliberately—I mean, it’s not like some one was moving it in, and set it down for a second.
Also…who in the hell would pay $300 for a high chair in the first place??

I used to work next door to a furniture store. Their dumpster was a treasure trove. I once found a box spring and mattress, still in the plastic that they had thrown out.

What on earth are some people thinking??
