First, some new technology comes along that allows something never before possible. Cash from an ATM, stock trading from an airplane’s aisle seat, ads next to Google search results.
The inventor or entrepreneur who uses the invention benefits from sales and wealth and hires people to produce the good or service. We don’t hear about this. Instead we hear about the layoffs of bank tellers, stockbrokers and media salesmen. So productivity becomes the boogeyman for job losses. And many economic cranks would prefer that we just hire back the tellers and toll collectors.
This is a big mistake because new, cheaper technology becomes a platform for others to create or expand businesses that never before made economic sense. Adobe software killed typesetters, but allowed millions cheaply to get into the publishing business. Millions of individuals and micro-size businesses now reach a national, not just local, retail market thanks to eBay. Amazon allows thousands upon thousands of new vendors to thrive and hire.
