Seems unfair to me also, but its their property. When I was a kid there was a corner lot in town that was very valuable. Some old man had owned it for years.
Every body at one time or the other tried to buy it, but he wouldn't sell it.
He eventually died and his heirs sold it in a New York minute! They made a bundle and he never saw a dime of it. Thats just the way things are some time.
Its capitalism spelled with a big C! KF
