I didn't say he was :) Would he be one if given the opportunity? Yeah, probably, but not by design. He only knows the business world, where the CEO is the king and there are almost no checks and balances in place to keep him/her from making terrible decisions. The only governmental structure that he would be comfortable in is as a monarch.
What he's doing now (probably) isn't consciously intended to create a dictatorship, but it's still the direction he's going because he's just trying to go about doing business. The problem comes when doing so consolidates power under the executive branch and renders the other branches' checks and balances either useless or powerless.
