Oh come on, it's _not_ about having people "remember who slighted them".
It's about not being a dick.
Most people understand this just fine - you don't be a dick to the CEO or the Venture Capitalist because you're not a dick. You don't be a dick to the waitress or the janitor because you're not a dick. It's pretty easy.
_Some_ people though, have to work hard at not being a dick to the investors 'cause there's something in it for them, and don't bother working hard at not being a dick to waitresses. The only reason they have any trouble with it is because they _are_ dicks.
And as the article and a lot of these comments point out, other people _do_ notice.
