"First rule of Economics 101: our desires are insatiable. Second rule: we can stomach only three Big Macs at a time"

This quote by Douglas Horton is an amusing method of illustrating the basic principles of economics. The very first rule of Economics 101 is that our desires are insatiable, suggesting that no matter how much we have, we will constantly desire more. The 2nd rule is that we can just consume a lot simultaneously, and in this case, the example is 3 Big Macs. This is a metaphor for the idea that our resources are restricted, and we can just take in a lot at once. This quote is a funny method of highlighting the standard concepts of economics, which is that our desires are unrestricted, but our resources are limited.
