That's correct Emmanuel, the pay is much better in the US with old world skills and shops that produce premium restorations for the well heeled can mostly name there price, good on em I think. The demand for perfection with an automobile restoration is very very high and the shops that can achieve it would right off hundreds of hours in losses on every job.
I'm sure it happens in the US too, where skilled craftsmen have business's and one day they just fold up, I think this happens because the man behind the work isn't a businessman at heart and its only half for the honest "traditional" craftsmen about the money, and more about creating.
