This stuff is hard. Creating something from nothing is hard. And it is exactly this degree of difficulty that demands that we not punish inventors, innovators, investors, businessmen, and those that would create that which currently does not exist with derision, high taxes, and the scorn that comes with getting rich enough to be catapulted into the top 1%.
If you want to punish people for trying to create the world of tomorrow, then you had better be prepared to accept that the world of tomorrow will likely be no different than, or worse than, the world of today.
