The King of England has money troubles?
Too many hangers-on.
This is what pissed off Harry. He had to go get a job.
The Royal family is being reduced to the immediate King or Queen and their children.
And if the King slashes his allowance he (Andrew) will probably find that he can no longer afford to live at the Royal Lodge (I assume he has a life time tendency).
That would leave him in a bit of a sticky wicket.
Since he (Andrew) never cultivated the art of making friends he would not be able to couch surf.
Might end up having to move in with one of his daughters.
