It should come as no surprise to anyone that doing ethical property development requires a transfer of wealth.
The status quo inherently disadvantages those who have less. So the ability to do make an impact is limited by the amount of value that is available. If a bunch of us get together with sticks, we're not going to build a brick house. Someone with a large brick house is going to have to tear down their second (or third, or fourth) home to give us some bricks.
When there's a fixed amount of something, those with lots have to give up at least a little in order to achieve genuine equity.
It turns out, do do things differently requires all of us. Change doesn't happen at a distance.
