Danny Alexander is frankly the most dangerous person I can think of in British politics. Well as long as you are hard working or aspirational that is.
In all the years he has been buggering things up for hard working people, I've never once heard him define EXACTLY what constitutes being rich. He's just another
PR man playing the politics of spite and envy.
Fortunately, he's unlikely to be in a position to do much damage after the election either because the Lib Dem plague will have been eradicated and/or following Devo Max and the inevitable consequence of a English Votes for English Laws he will be neutered as MP for Inverness.
