... is a little like asking whether there are universal, objective principles of economics. Sure, in one sense there are: but they're not the sort of applied advice that people making moral or economic claims are usually looking for!

In seems in economics without much of a stretch you have things like:

• buy low and sell high

• don't produce items for sale at price x that cost you y>x to produce.

• don't buy a productive asset that produces c cash per year for more than c/i where i is the risk free interest rate

I'm not saying I can do this trick with morality, but economics seems to produce piles of actionable results.
