Except when “we” preach it:
It’s better for the economy. When you buy local, a large percentage of the money stays in your community. The farmer can afford to have the local mechanic fix his truck, the mechanic can afford to hire a local accountant to do his taxes, and the accountant can afford dinner out at a local restaurant. The wait staff makes decent tips, and the restaurant can afford to buy more fresh, local food to serve. Money also trickles into the local infrastructure – improvements to the public park, funding for academic enrichment, and so on. Everyone wins.
By the way, I would really appreciate it if you could find me a good economics textbook or popular treatment (such as this or this) that actually uses the term “trickle down economics” in any way other than describing the term as it is used popularly. In other words, I attended 9 years of college and graduate school, and have taught for nearly a decade, and in all of that time I have never once encountered the term “trickle down economics” in any reading or at any seminar I have attended.
UPDATE: this just hit my inbox
OK, back to more important things…
