They are not hard to find. Many areas of the country have poor neighborhoods, unemployed parents, disabled parents, and very little to eat. Have you ever heard of the people that live in the Appalachian Mountains? A little research will reveal poor and depressed areas all across this nation. You may not see them with your own eyes, but that doesn't mean that they don't exist.
Also, entire families are homeless, living in tent cities, and some even eating out of trash cans. It wasn't that long ago that many food pantries had empty shelves. Have you even seen the crowds that gather when churches hand out donated food? Have you even seen little kids panhandling outside grocery stores? Have you ever heard of community food drives that gather can goods for needy families? Have you ever heard of kids getting their only meals during the day while at school?
Believe me, the poor do exist, and their numbers are growing as we speak. A little research may open your eyes to the poverty in this country.
