Donuts, expanded

I’ve been thinking a lot about sustainability and whether we can truly declare ourselves devoted to advancing the cause. After all, sustainability means in one sense the ability to have all your needs met through local gardens or farms or ranches. And after all, the number of people in this country that are truly capable of such a feat is very small.
So does that mean that sustainability is only achievable in certain levels of success?
One such sustainable theory that I’ve been mulling over is the ‘support the local businessman’ over the large retail chain. One of my favorite vices is donuts. Thus the cause for the previous post. Thanks, Heidi, for spurring me on to complete my thought. So I’ve been looking for a donut place in my local area that meets the criteria of small and local and not chain. However I’ve reached a quandary. There is a local chain (rather large, but only in this town) that is essentially a donut-monopoly. Do I patronize their establishment because it’s local, or spurn it because it’s a monopoly?
I’ll let the readers of this blog, if any, decide.
