As long as Michael owns the Beatles songs, he will never go broke.  He may not make as much money as he used to, but I believe he still has a little bit of money in the bank.  And I wish he will dump Neverland--he hasn't lived there in three years.
I also believe that part of the reason that Michael has had the money problems he has had is because he has been taking care of his family.  I would have made sure that Joe and Katherine would have been set and the rest would have to fend of their own.
And I don't believe that Michael would sabotage his siblings' career either.
