You can't blame Germany's problems on liberal policies, it's far more complicated than that,
a/ it's paying a high price for re-unification and
b/ it's facing difficulties with adjusting to the global market, it's also not prepared to pay the price of adhering to the dogmatic single mindedness of the single currency.
Whilst we may be doing better it's only because the changes required were forced on us by depression.
Most of Europe also faces problems with former S.U. citizens working for lower wages than our equivalent
Now as for reliability of American products I've already mentioned elsewhere that I won't buy Dewalt products anymore
a/ they're just far too expensive and don't last, the last Dewalt Drill I had was on its last legs within a short space of time.
b/ They're an immediate target for thieves over here
After the last one I had got stolen I bought a Chinese made equivalent for £40, the Dewalt costs over £300 here. It doesn't take a genius to work out that the £40 drill to me makes far more sense economically. I suspect most consumers including those in the US are of the same opinion.
