I really used to try to buy American-made. I still make some effort, but in most cases it's so pointless that I don't even check.
There's different rules in different countries. I bike. The vast majority of bicycles are made in China. There are some bicycles made in the US. Trek, I think still, makes some of its very expensive, carbon fiber bikes here. The former Schwinn Paramount factory (their best road bike back when Schwinn was still an independent, family-owned company) is still active as Waterford Percision Cycles, a very small company co-owned by Richard Schwinn. But anyway, Italian bikes are often thought of as world class, a think to have among serious bikers (I'm just a casual bikepath guy). These "Made In Italy" bikes? Well, according to Italian law, a products can be branded as "made in Italy" if the most labor-intentive portion of the effort is in Italy. The frames and components for a lot of famous Italian cycles are - made in China. But they're branded as Italian-made because the custom paint job was done in Italy. So it takes longer to paint than to manufacture and it can be branded as Italian. But it's misleading.
