Nice find!!!
For those that aren't aware, public schools have laws that prohibit them from easily and efficiently reselling items deemed "surplus or trash". While the globes look nice, they are becoming an item that just takes up space in a classroom. With google Earth and the technology age, they are no longer a necessity in a classroom.
Some schools also have laws/policies restricting them from just giving them away. Sometimes the best items are sitting there in a school dumpster just waiting to be found.
Is it a shame...yes. Is it the school's way of wasting tax money, NO. If you don't like it, go to your local school board meetings and voice up your opinion on these policies and fight to change them. I work for a school and I cringe every time we throw a bunch of good stuff away. Of course, I usually bring the truck to work the next morning and show up early before the garbage man gets here
