Having never been around the West Coast tech scene much, it sometimes seems that there is almost a tacit expectation that someone "owes" you money for your idea. Without commenting on whether that is "bad" or "good", it's just interesting to compare it to the attitude most of the people I know who start businesses on the East Coast who would find it at least odd if not right outlandish that someone would give you money before you demonstrated in some concrete way that you have the ability to tender it back with some form of interest.
I don't know about the entitlement you describe, but isn't getting in on a startup more about 10x payouts instead of incremental "interest" payouts? I can only imagine a VC is not interested in a concrete demo of marginal profitability, and would prefer a pitch for some disruption that has some worthwhile chance of success.
Different types of investors attract different types of entrepreneurs would be my guess to explain the difference you see.
