Beyond a certain point that makes him stupid. He is most definitely a sleazy NYC real estate developer (which is redundant because they all are) and a sleazy reality tv star. He is also notoriously egotistical and thin-skinned, and is beginning to show signs of the same paranoia that destroyed Nixon.
Okay you claim ALL New York Real Estate developers, are sleazy.
I claim all lawyers are sleazy. I claim all politicians are sleazy, too. Around half of federal legislators are lawyers (provable).
Neither of us can "prove" our claims, and attempts to do so would most likely achieve nothing.
* Many people love their homes, which were built by real estate developers. Those developers, all across the country, had to deal with sleazy career government employees, and lawyers. That they put up with the process is a testimonial to their pragmatism, intelligence, etc.
The professions which seek to impede development are career government employees, sleazy politicians, lawyers etc.
Pick your side. Personally I see a lawyer calling a politician "real estate developer" sleazy as on the ridiculous side.
I am with the developer, at the end of the day. Developers are entrepreneurs, that add value. Lawyers are parasites, that attach themselves to people, processes, institutions and suck on their lifeblood.
