Although your implication that had the woman kept the copper coins for herself she would have improved her chances of "making a living" indicates that you don't really understand the situation of a widow in Jesus's time (women had no rights, they were defined by their husband. A widow has no husband, she is [censored])...I simply disagree that "Giving all you have is not terribly meaningful if you have nothing to give." I think it is incredibly meaningful (to be fair, so is giving all you have when you have lots to give).
