I still don't understand the hyperfocus on cost savings without looking to increasing income.
For a startup, saving costs allows you more time to try to develop product-market fit and thus increase income. In the long run I'd far prefer a $10m revenue, $1m costs business to a $100k revenue, $10k costs business, assuming I have the same percentage ownership.
Same thing with life -- if I can make much more money by living in a place like SF or NYC, it's more tempting than living in the midwest and making much less. iPods still cost the same in NYC and rural Iowa.
