Land shouldn't be owned indefinitely and passed through families. It's not right to have created a dynasty based on one guy in the 1800s claiming everything in sight and having his idiot descendents be wealthy simply based on the fact. They didn't do anything except inherent land.
Land that isn't your primary home should have to be leased and not owned, that way it's being used most effectively and not privatized for the sole benefit of the owner. It leads to land speculation and squatting of land that someone else would like to use.
Additionally, natural resources should also belong to the people and companies should have to pay fair compensation for their extraction.
