why land rent is inevitable

In today's news, China has backed off a violent land grab, after video was shown all over the world. Information makes all the difference. Remember the American home video of cops beating up a black man? Or the pictures of napalmed children from Vietnam? Or the pictures of Nazi death camps, or tanks in Czechoslovakia, or hooded prisoners in Abu Ghraib? We don't accept stuff that we used to accept. Information makes a real difference, and available information is increasing. The world is moving in the right direction:

“The Stockholm International Peace Research
Institute (Sipri.org) and Canada’s Project Ploughshares both annually track
the number of armed conflicts taking place worldwide. ... In short, there
are fewer wars, fewer arms sales and fewer people dying, each year, than at any
time since the second world war." (source)

Up until a hundred years ago, genocide was considered acceptable to most military folks in the west, the class system was rigidly in place, women had few rights, and everyone thought that was normal. But as people get more information they see the benefits of behaving better. And that is why, even though it might take generations, I am confident that justice will increase until it is applies to everything.
