Often new citizens of America take their freedoms far more seriously than individuals who were born in to it. Some of the most patriotic people I know are naturalized citizens or first generation citizens. In addition if you built your wealth with hard work and sacrifice you are more appreciative of it. Familiarization or ease of acquisition leads to lack of appreciation.
Like some smart dude said:
Hard times make hard people
Easy times make soft people
Soft people lead to hard times.
