In my world, anyone who has a credible idea and meaningful traction can get a meeting with most VCs fairly easily. Are you suggesting that after such a meeting, an investor would refuse to fund someone with a good idea because they're not enough of an asshole or connected to the right people?
There's no need to be so dismissive so quickly. Our perspectives on the world are formed by reference experiences. I've seen numerous entrepreneurs come to Silicon Valley with absolutely zero connections, work hard to build a real business that makes real money (I'm talking B2B/SaaS products, not trivial social media apps), and raise funding from top tier investors when they had enough traction.
Perhaps you haven't seen this phenomenon. That doesn't mean it doesn't exist. This is most heavily rooted in Silicon Valley culture, but I'm sure even in New York and elsewhere, the fastest way to get ahead, build your network, get connected to the people who run the world, etc is to be as helpful as possible to as many people as possible and know that eventually the rewards will come back to you.
The above statement may seem to you full of naiveté and wide-eyed optimism, but that's the optimal strategy for success for even the most hardened cynic; look up some research on persuasion through reciprocity and liking.
