Google and Mozilla are competing in the browser market so it's pretty reasonable to compare their investments. I don't understand your reasoning here.

My reasoning is that Google's investment is massive and just because they're throwing money and people at a problem doesn't make it necessary for everyone else to do so as well.

True, but when you say:

>Other browsers do just fine with significantly fewer engineers

It implies that you have any examples.

Safari.

Fair point :)
