There is a very small population of poor in La Crosse. The city has a very low unemployment rate and only a tiny (less than 5%) minority population. Most of the fat people are fat because they eat too damn much. Certainly, that includes a lot of junk they shouldn’t be eating, but it’s not because they couldn’t be eating nutritious food.
According to the US Census, La Cross in 2008-2010 had about 14.3% of families and 24.0% of the population below the poverty line, including 25.8% of those under age 18 and 10.2% of those age 65 or over.
The best way to find out the real story is to ask some clergyman, who have a much clearer view of how much poverty and hunger is there, because it is indirectly related to their job.
