I can only think it began with the philosophy for making better decisions, solving problems, and improving society - particularly in the allocation of its resources.
As so, I think a huge part of the problem with economics, including most economists, is that people equate value for wealth. Value certainly is subjective, I mean, do you value having $80k, or a nice car? How about a pool, or a boat? Do you value your time less than the cost of a flight? All very subjective. But I think it's flawed to conflate value for wealth. Wealth is something real, the things you are evaluating in trade. Time is wealth. Money is wealth. Oil is wealth. Land is wealth. Why don't we simply measure these things, and how they're allocated? IMO, it seems more practical and more noble of pursuit to figuring out if someone actually needs food in society, rather than what people with plenty of resources ascribe their values to.
