I wouldn't worry so much about a Top link... but there are still made in USA implements and Tractors. I don't know about you ,but I would like to keep my brothers working, so I buy made in USA if available.
With a Global economy, the natural order of things makes products, and USA manufacturers vulnerable to displacement by cheaper and perhaps even better products from abroad, some subsidized buy foreign governments.
We as consumers and Americans need to balance our objectives with the big picture and the long term benefits to of us as individuals, as well as to our Country.... the Greatest Country on earth USA..!!
