Both Germany and Japan protect their workforce from off-shoring and business visas and their economies are quite healthy.
Both those claims are false.
Neither Germany nor Japan have successfully protected domestic production.
Japan particularly has engaged in massive outsourcing, as labor costs have risen.

Germany too has engaged in outsourcing to Eastern Europe since the fall of the Soviet Union.
{They find that, in Germany, the extent of outsourcing among manufacturing industries is higher than among service industries}

Further, to call the Japanese economy "healthy" is laughable at best. This is a terrible time to do an analysis on Japan due to the havoc from the Tsunami - still, Japan has not had a healthy economy since the 1990's.
In fact, the wealthy elite of Japan have been attempting to do to their workforce what the US has done and the Japan have had demonstrations.
In fact, China and India do the same even though India's economy is a reflection of our since their major income is servicing a smaller and smaller US consumer market.
Excuse me?
The consumer market in the USA is growing at about 2% a year (which is dismal, but Obama is running things)
The talk of the US collapsing if we stopped destroying our Blue and White collar force is nonsense and is meant to protect upper level wages and bonuses.
The days of button pushers making high wages are over - and will never come back. The myth that white collar jobs are declining is propaganda.
We are in a global economy - it is a matter of fact. The USA has significant assets and can (continue to) dominate this economy - BUT it must be through innovation and creativity. The idea that a union slob with a 6th grade education can push a button on a press for 8 hours a day and live a middle class life is over.
Get a degree in engineering, IT, or business - and you're golden.
Switching gears a bit; we stand on the brink of a revolution that will dwarf even the digital revolution - this is of course the biotechnology revolution. America DOMINATES this field and is poised to reap the economic rewards of these innovations. Of course we have Obama, who will seek to sink the American dominance and socialize biotech under his fascist care fiasco - but IF the leftists are driven back, the USA will be in fine shape for many decades as biotech advances.
