All well in good, but how much does Germany give for Europe's defense or to further the Western world-aegis?
Who will carry that torch if the United States puts it's already poor "bang for the buck" military further into decline?
No one? The populous answer is SURE, however, the united elite answer is a resounding "No." In the short term the USA was not designed to have a social welfare system that has distinct pros and cons.
Pros:
Provides something closer to an equal economic environment.
Provides a stable health, economic, and other system for most classes.
A clear expectation of what will happen in life
Cons:
Costly. Cutting down on the whole empire business.
The stability reduces the competitiveness in most environments leading to malaise that one's life will not change.
A bureaucratic system that will dictate more of life. Stability again, but at the loss of autonomy and freedom of choice.
As well, you need to mix the system to meet the cultural environment.
For industrious and serious minded Germans who consider rules and time keeping to be a form of religious piety, the system tends to work in a more fulfilling matter.
Converting hyper competitive (And now privileged expecting and privileged obsessed Americans mixed with many cultural and ethnically divided underclasses with mixed educations, motivation, and other factors...) American system to fit would be very difficult.
We would probably just propagate the bastardized system that further divides the classes among the Whole Foods/Walmart divide.
