These newspaper rich lists are 100% made up.
I imagine MK spent a lot of his wealth building BG.
His ex wife would have got half of the big 80s money.
The rich lists are not 100% made up they are based on mainly publicly available company accounts and in the case of musicians for example the earnings are not hard to find either.I would say 70-80% accurate.
You can see how much money his company makes in a given year but you have no idea what he spends his money on so that info is worthless.
If he earns a million and spends a million on crack and whores, how much is he worth? Or if he bought a house for a million the sold it for ten 5 years later? Complete guess work.
