Having a vision and making money aren't incompatible. Every step Microsoft took towards a computer on every desk was a step towards a larger customer base. Microsoft identified a large trend in computing early on, and made money off of it. The same is true of Google, and pretty much every other large tech company out there.

Visions don't have to be altruistic. Having a vision just means that no matter how successful you become, you know what your next step will be.
