Not just labor -- expertise. Also, do you have access to fully furnished kitchen? Living out of a car or in a marginal housing situation where a kitchen isn't available (or you've got a microwave/hotplate and fridge) changes some of the cooking.

These considerations aren't conclusive, and I'm sure there are people who find a way to overcome them, and possibly we could use resources that help others to do so.

But on HN of all places people should understand the power of marginal gains. And marginal obstacles.
