Future Danger ?
I believe that going forward USA will begin to look more and more like Latin America than Latin American countries looking more like USA.
One thing that has kept the USA strong and a wealthy nation is the governments ability to collect taxes on so many levels. Paying taxes to the IRS voluntarily at end of year is a success that does not exist in any Latin country on this level. All we can hope is they spend the money wisely.
Anyone who has crossed the border to Mexico can see huge differences in level of wealth. Even when I used to travel to Montreal from NY I would notice differences in quality of the roads and that there were no street lights on Canadian side.
One danger I see on the horizon for the USA that is somewhat common in Latin countries is the asset purchase and hiding of money in offshore banks. Wealthy Latinos have always invested part of their funds overseas for protection from shaky governments. Since the wealthiest 1% in USA are paying almost 42% (and increasing for last 20 years) of the taxes in the USA I think is only matter of time that you will see more citizenship renunciations. We are looking more and more like some Latin countries in this regard. I can envision many more of this group taking their money out of the USA. We are increasingly more dependent on the top sliver of the wealthiest and this is growing. Even Romney took 50 million USD to Bermuda and one of the founders of FaceBook renounced his US citizenship for Singapore to keep most of his $500 million windfall.
So the stigma of this is eroding plus the fact that almost 5% of middle class folks in USA are behind on their mortgages. Some have not paid in years and is a 'business decision.' to not pay.
Americans in the past have been reluctant to learn about other countries and certainly they have had the lowest percentage of Passport holders as a percentage of population. Many wealthy people in their respective Latin countries do not want to pay taxes because they do not want it to go to the poor (or to their corrupt governments). Many Latin countries have historically received a larger revenue share from Customs duties, and collect very little as a percentage from the poor majority.
What is keeping US citizenship worth besides a promised SS check in the future?
