For example, aside from the dozen or more web companies I know who'd love to be hiring programmers and expanding their business, there's also me, a lowly moonlighter. Were I able to hire and build my business to the point of profitability in the near term (I've yet to launch), I'd be able to hire still more developers to further the business and so on. Which all goes to say that there's not a fixed supply of jobs we're fighting for. We're working towards value, and value has a way of building on itself. If the software industry can create more value with those incremental workers, then the migration is good for us all.
