If we're discussing legendary ruling elites like the Rothchilds. Their strategy may be to control money supply, central banks, regulators, issuing of currency. Et al.

There's always a question of who owns private institutions like the federal reserve. Who directs banking cartels. Who dictates European Union policy behind the scenes.

I think buying and selling hotels or common stock could be a little beneath them. Whoever owns the federal reserve could be the type to aim higher than that.
