> I think the answers “yes”, if the demand is there.
It's not a question of demand. A negligible number of customers care where their product is manufactured. They care only about price, which is why manufacturing moved overseas in the first place.
What is needed to manufacture phones in the West is protectionism and mercantilism. Our governments would have to subsidize domestically manufactured products, require the use of domestic products for various industries, and tariff those manufactured in countries with lower labor standards and incompatible civil rights.
Unfortunately such policies lead to higher costs for consumers and lower economic growth. It's politically unpopular for the same reason action on climate change is unpopular: it makes everything more expensive. It's no wonder that virtually all western politicians support neoliberal globalism. Goods are cheap, even if it means some of us lost our jobs in the process.
Worse, these policies also tend to lead to war. One of the big reasons we've had relative peace between world powers for the last 75 years is that our economies have become closely intertwined, so no politician or corporation can stomach the economic costs of war. If global trade starts to break down we'll head directly into World War 3.
Personally I think we should embrace protectionism anyway despite the cost and risk. I'd go so far as ripping up NAFTA. American labor standards are so shit that Canadian companies can barely compete, and it's holding us back from progressive policies like a 4-day work week. Ontario can't even mandate paid sick days! I'd rather we have a well-paid labor force than cheap groceries and electronics. Unfortunately no politician agrees with me.
