this is not destroying things to create jobs. this is about globalization negatively affecting local culture. clothing especially represents culture. if people can not afford to create their own clothes then that has a negative effect on their culture as a whole.
I don't see how localized culture clothing styles would be destroyed by importing different styles from other countries.
nobody buys the local style because it is more expensive than the imported stuff. as a result the local style dies out, or it doesn't get a chance to be developed in the first place.
Preventing imports will force them to pay the higher prices for the local stuff.
Maybe it's better to let them decide what they want to buy.
