He wanted to feel powerful, like he did in the White House. By having such things he didn't have to admit he that was, and is, a loser. Being a loser is what he fears more than anything else. He dodged the draft (not that he would have gone anyway if he was drafted), he's been married three times (?) and had God alone knows how many trysts and affairs, he's driven others into bankruptcy and out of business (generally small businesses who he wasn't going to pay anyway), and used the courts as his private weapon.

Losers do these things, and then they bury an ex-wife in a section of one of his golf courses designated as a private cemetery and thus probably non-taxable.
