I've actually found the image of Silicon Valley as a hotbed of money-grubbing tech people to be pretty false, but maybe that's because the people I hang out with are all really engineers.
We get the worrywart, the hypochondriac, the money-grubbing miser, the intractable negotiator... Some would say certain of these refer to the stereotypical, or 'stage' Jew. But objectively speaking, the only crime in humor is an unfunny joke.
Money has never made man happy, nor will it, there is nothing in its nature to produce happiness. The more of it one has the more one wants.
