Who don't? Governments certainly do. Food is commonly subsidised so that domestic production is maintained. Oil is commodity number one in governments exerting influence to control it. I'm not so sure on computer manufacturing.

Or if not subsidized, then subject to enough import restrictions that domestic producers survive. I'm a pretty hard-core free trader, but in this case I think some restrictions to ensure a local industry make sense. You shouldn't have to starve or freeze just because other countries close the border. Security comes before prosperity or you're partying on the Titanic.
