To make the switch, visualize what the rotation you will see if you are standing above her looking directly down at her or from below her looking directly up at her.
The most sucessful VC companies are the most innovative. They produce a product or service more competitively than the alternative at a cheaper cost.
Companies which consume these products or services save money. As a result they can offer their products/services more competitively, which results in hiring (or at the very least fewer layoffs).
The bottom line is that innovation acts as a stimulus in times of recession. During times of expansion (when the economy is at full employment) it simply results in increased standards of living. I agree with barbie17 that the unemployment rate is more or less constant in the long term.
The VC industry is at the heart of creative destruction. And the job creation that results goes well beyond the jobs created in the VC companies themselves. There is a trickle down effect.
