"Don't they derive all of the same benefits of living in this country as a more wealthy person?"
.
Actually, no they don't. Part of living in this Country is doing business in and from this Country. And therein lies the biggest difference. An $8/hr part time burger flipper is not likely to be deriving millions of dollars worth of benefit from the government creation, maintenance, regulation, and protection of ports, airports, and the like. Nor the benefits of government support of international commerce. Nor the profits from selling the government billions of dollars worth of goods and services. Nor bailouts of TBTF financial institutions. Nor of agricultural price supports. All told, there are a lot of benefits (worth a lot of money) the wealthy derive from living in this Country that the $8/hour part time burger flipper does not.
