I'd love to be able to know exactly what Steve Jobs and Bill Gates were thinking when they started their respective companies, but I'm pretty sure they had bigger designs than what you're suggesting.
You're probably right, as my psychic abilities and time travel skills have been failing of late...I can't imagine any rational business owner not wanting as much money and market share as possible. I know I do.
Well, as long as "as much money and market share as possible" doesn't equate to "growing as fast as possible." There are plenty of 'conservative' businesses that avoid growing fast like the plague. Risk management and all that.
