If there is no money being used inside the Federation, how do they distribute goods or determine how much one can own, eat, or possess?
As an example, someone who really likes food would want to consume more than the "average" person and therfore his montly spendings on food would be much higher (let's throw away really specific and weird situations and focus on general rule). Today, we'd work to get money, we get money and have it to be more or less able to buy food, more elaborate living quarters, or other essentials and luxuries.
How do they handle this in the Star Trek universe, if there is no money to mediate that distribution of goods? What prevents one person from getting much more food than an "average" one, while working much less than him?
