Your second point has nothing at all to do with your first point (unwanted mail); and is barely the USPS's fault. I disagree with letting the "market" decide when it comes to vital infrastructure (mail, internet, roads, telephone, electricity, water) because the "market" is not always a healthy place (e.g. see US internet/cable/telephone market, see UK train market, et al). It is one of the few areas where a state run monopoly might actually help business. While it certainly hurts opportunities within that specific sector, in really helps other businesses in other sectors compete globally.
