Why do people give expensive gifts to wealthy people?

As a guitar player it pisses me off to no end to listen to Howard rattle off the names of all of the people who have gifted him extremely expensive guitars. Billie Strings sent him a crazy beautiful guitar and Howard didn't even know who he was. Had to go look him up.

Then Howard went out and bought a Gibson, Martin and a Taylor so the really sad thing is most of those gifted guitars will never even get played. Just hanging there on the wall like expensive trophies.
