Actually, this is a sound strategy and a smart one if -- and only if -- the industry the tariffs are designed to protect grows and thrives to the point where economies of scale and buying power kick in and consumers benefit from the costs savings. Otherwise, tariffs simply serve to penalize consumers by denying them access to more competitively priced goods.
Regardless of what some may think, a strong industrial base is still critical to the economic strength of a nation. Just look at the United States -- when your industry vanishes, you are in trouble. You simply can't build an economy based on selling foreign-made goods to each other. Manufacturing provides jobs and builds a wealthier consumer base.
