I think you're greatly exaggerating. The government doesn't manufacturer appliances, or anything else for that matter. Isn't it up to the manufacturer to produce a quality product? My appliances don't break after a few years, and I have no shortage of options when it comes to vehicles.
The bottom line is that the government has a responsibility to ensure the environment my family lives in isn't needlessly polluted by those wanting to save a dollar. Companies have repeatedly shown they are unwilling to self regulate, and any company that does is likely to be at a disadvantage due to the increase in costs. A government regulation is actually the most fair option because is creates a level playing field. Until you start factoring in international trade agreements, but that's another issue.
