I thought it was a good article.
It brings to the surface some of the real reasons people (Americans) get upset about the topic.
But I think some of the racial and ethnic links are not so much the reason now days.... at least for most people. It was more so in the past perhaps
Americans, in general, disdain anyone they think is freeloading.... especially if they think they are paying for it. (talking hand out.... not hand up).
But the immigrant link was over done. And the comparison to Europe was a little off (by way of comparison).
America never had kings (monarchs), noble class, feudal systems where there are a very few extremely wealthy and all powerful people and many others were serfs or served at the pleasure of a few.
(unless of course you work for a fortune 500 company
Europeans and their systems evolved from a different starting point. They come from a system where wealth and power was often not acquired through some level of effort.... but inherited and sometimes passed along across centuries... a caste system.
I believe their system is heavily influenced by, what they believe, was a past gross imbalance of power and wealth with no chance of escaping it.
