just realized
When Jacob asks if Brett collects, Brett goes on the offensive and calls people that collect as being obsessive compulsive and a variety of other obscenities. In Wall Street, when Bud Fox goes to the Gordons house to sign some papers and meets the Darien (?). Bud Fox calls out Gordon's lavious spending but Darien calls Gordon "one of the most astute collectors" she has ever met.
When Brett was calling out people that "collect things," was he solely referring to Gordon Gecko?
