This idea sounds awful. I don’t think that will happen. And if this happens, then only by the stupidity of people.
If the land is wholly owned by large corporations, then corporations can dictate their terms, they can impose what is beneficial to them. They can do the most terrible things with impunity, because it is completely their city.
If you are interested, then right now (for a very long time) the same thing happens only in a slightly different way. The world is now ruled by just a small group of large corporations and various foundations. They promote sinister ideas that harm people and keep 99% of people enslaved. Bad food, water with fluoride, senseless activity, poor ecology, constant millions of times over-emitted electromagnetic radiation in cities, etc.
A person and family should be in the first place. Otherwise, there will be slavery, which is now happening at the moment.
But I don’t think that everything is so bad. More and more people are waking up. Everything will change soon. I have no doubt whatsoever.
Ofcourse.
I think it's better to concessions lands to such corporations rather than sell them. The lands remains community-owned but run by the corporations. Nations will likely not even like the idea unless maybe citizens are part owners of the lands.
I don't think corporations should be buying up lands otherwise they may buy up the whole earth and destroy or turn it into something very unhealthy.
They should be well governed by the right rules to prevent them from acting outside the law.
