Which is why economics will continue to confound you. How much I want one apple can't be measured and compared to how much you want an apple, or how much either of us would want a hundred apples. Valuation is subjective and as importantly, temporal. Liberty lets the individual use their talents to satisfy their wants as they see fit, you're trying to pull the levers of government coercion to get an outcome you desire, your fellow man's liberty and desires be damned.
The mathematical approach to economics was attempted by the GOSPLANners, who were confounded by reality at every turn. You want to substitute your wisdom for the wisdom in action of 280 million independent and free human beings. We're just so many cogs in the machine you envision as the economy.
