> Yes you should. Bob supported a host of vacation-related workers and kept the economy moving. You sucked money out of the economy and sat on it. Eh. I'd rather say that Bob diverted labor toward supporting his luxury consumption, whereas I made capital available for increased production (of cars, houses, food, etc.). The truth is somewhere in between. I think your read on this is a little too simplistic.
It seems to me that the burger Bob bought (and the check the restaurant wrote to its supplier for the ground beef, and the check the supplier wrote the farmer for the cow) is a direct payment into the food production system, while 'making capital available' may or may not land anywhere near the real economy. What's the sophisticated view here?
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.
