Neither is generically healthier considered in isolation. One wouldn’t want to strictly focus on replacing imports, or maximizing export value, but doing each when it’s more profitable to do so.
Export orientation seems very bad for e.g. child care when fertility rates are below replacement & educational institutions have almost uniformly been deeply sabotaged. OTOH it would be stupid for most groups to try to grow all their own crops.
The Rationalist movement is explicitly premised on the idea that people seeking to do well on crucial decisions can and ought to do a lot of import replacement with respect to knowledge at least temporarily.
I don’t see how to interpret those verses any other way, which is why I strongly hold my opinion rather than cousin_it’s.
