My self-interest? I'm gainfully employed and not on the dole. I directly employ two others. I buy a lot of materials that require very skilled labor to produce. (American labor I might add.) I make a product people want - They wouldn't buy it otherwise. I donate well more than a tithe to charity These are all valid contributions to the economy and my community. Why should it only be about my self-interest?
If I wee being purely selfish I would want fewer potential competitors edging into my market.
