If you want to argue general economic principles, then do so [1]. Just don't cherry pick examples to prop up your perspective. I don't think anyone, even Reagan or Thatcher, would have stood behind the assertion that a luxury phone and computer maker with a hoard of cash would benefit the poor. You're attacking a strawman here.

[1] Just keep in mind that "trickle-down economics" is a political philosophy, not an economic one: http://www.tsowell.com/images/Hoover%20Proof.pdf (footnote on page 2)
