I doubt you can put a price on what's a reasonable price to pay for 1 minute of time with a member of your family. Is asking someone from your family to go with you to the gas station to fill out the tank while you chat about your day a reasonable way to spend time together?

This market mentality doesn't (shouldn't?) apply to social relationships because it leads to stupid decisions (like to give your CC number to a stranger). Next thing you're weighting how much your family time is really worth vs. making another buck.
