Capitalism's prime directive is growth. Efficiency matters only when two conditions are met: 1. There is sufficient competition 2. There is resource scarcity

Capitalism's prime directive is growth. Efficiency matters only when two conditions are met: 1. There is sufficient competition 2. There is resource scarcity In the current context, the first condition holds true for Dropbox, but the second does not. There was a commenter here on HN a few months ago who works in VC, and he/she was saying that VCs currently have too much money and they are desperately looking for things to throw that money at. That is the opposite of resource scarcity. Make no mistake though: if and when we get the next economic crash, I think we will see a drastic shift in how tech companies operate. I suspect that a _lot_ of fat will be cut, then.
