Was going to Miami the best basketball decision Lebron made?

really im disgusted that people critise him for leaving, now im no lebron lover in fact i hate him 2nd most behind kobe but seriously he obligated his contract and had every right to leave, maybe he does want to play with 2 stars, hey i would leave cleveland too if i ever lived there, now let me put this into a real world scenerio, you get offered lots of money to be a ceo of a company and yet be unhappy, or take a low paying job as a garbage man and be happy, its what he wants to do and hes happy where he is
