I think its possible to bring the ecosystems back - but you have to start at the top of the chain, and work backwards. Not at the bottom up - make a price competitive business with foreign made bits, and eventually thru protectionist trade policy, bring back lower and lower parts of the supply chain - we may find it makes sense to stop half way down, and not try to bring it all back - we may not.
