There's an enormous amount of complexity here. For one thing, it's not like there is an infinite amount of beef available at a fixed price. Bob's eating that burger probably on the margin increases the supply of beef, but it also on the margin increases the cost. Now everyone else has to pay 0.0000001c more for their hamburgers. Or what if Bob bought a filet mignon instead of a hamburger. Maybe farmers will now be (on the margin), breeding cows that produce less hamburger but more steak. This could increase the price of food that poor people eat. If Bob buys a Tesla, maybe Bob helps expand the supply of Teslas, but now buying a Corolla is slightly more expensive, because there are slightly fewer economies of scales in sedans. (This is actually happening, BTW, as Americans buy larger cars.) I also spoke of Bob taking a vacation. He spent a thousand dollars on plane tickets, which has serious deleterious environmental effects, and for the most part represents a purchase of oil, not labor services. Oil workers wages may have gone up a bit, but most of the money just went into the pocket of whoever owns the oil. These are just some examples of possible things that could happen. Without empirical testing, we could not know what the exact impacts of any given decision are, and realistically, we do not have the resources to track the impacts of each decision through the economy. |
I could be completely off here but am interested in opinions on this.
