Now imagine you spent a lot of money to get a house with a nice view. Suddenly Larry Ellison decides to build a skyscraper next door, which blocks the sun on your property every day. You can't even grow flowers anymore because there's not enough sun. Some of your trees die. Are you happy?
Now imagine you spent a lot of money for your house. A housing company proposes changes to the neighborhood that will reduce the value of your house by 20%. In other words, you will be working and paying for years on a portion of your house that no longer has value. Are you happy? Well, maybe you can handle it because you're rich.
So these are the kinds of things that go through the minds of NIMBYs.
