[Star Trek] What are the limited resources on Earth? How are they distributed amongst Earth's population?

Money is no longer used due to almost inexhaustible energy and replicator technology to create food/oxygen from energy.

But although energy and food are no longer limited, resources like land space, or access to live renditions of a Mozart concerto would be limited.  What are other resources that are limited, and more importantly how is access to these limited resources determined?

The biggest thing to remember about Earth in the 23rd or 24th centuries is that Earth is literally a paradise. It's a technological and ecological paragon that most other planets could never dream of equaling. No human living on Earth wants for anything. Even living space isn't that much of a big deal. You have free access to go live on a colony world that's ALMOST as good as Earth, or you could travel the stars as much as you wish. 

What is probably the most limited thing left on Earth is society's patience for people who take advantage of this situation. Humanity suffered more than any other species to get to this point, and even centuries later still haven't forgotten the lessons of the 20th and 21st centuries. Everything is provided for an Earth-born human, literally everything. But they're expected to do something with it. Push themselves, be greater than the generation before. They have their material needs taken care of, it's up to the person to give back and show thanks for the gifts given to them by their ancestors. It would be SO EASY for a person to sit around on Earth doing nothing, or possibly sitting in a holodeck forever, but they would face the gentle but inescapable pressure of society at large to break this trend. 

Even though humans are beyond petty things like racism or prejudices based on other inborn traits, they can still be pretty judgmental about other people's choices, opinions or ideas. (Just check out how people treat Harry Kim sometimes) If you tried to live in a holodeck on Earth, you'd eventually find it turned off and a medical professional waiting to give you counseling for holo-addiction and ways to cope. It would be friendly and cordial, but you'd get the underlying message: We demand you succeed.
