1) The Post Office exists to enact a requirement in the Constitution but I'm not sure that means anything anymore. We could expect: 1) An increase in delivery costs in general, due to loss or restructuring of a competitor with relatively low prices and the market, like so many in America, not exactly being robust in the competition department anyway, 2) Possibly a near-total end to mail delivery in rural areas, 3) if not #2, it'll probably be because Congress authorizes the government to pay way more than the same stuff from the current USPS costs, to pay private companies to handle rural delivery, subsidized by urbanites (as it already is, but this'll cost more). In short, the likely outcome is somewhat worse service (outside chance of much worse service) at higher total prices, plus another claw of private industry in government, wasting our money and making our lives worse, that they'll fight hard to keep there (see also: HR Block) 2) Amtrak is not in the constitution. Privatizing it certainly means most routes close (I'm pretty sure lots of lines only exist to buy support from Congress—they're awful, talking routinely delayed by 50% or more of the stated travel time, because they don't have right-of-way on their tracks and have to defer to freight traffic, plus they travel slowly even when under way because they're on freight rails) and maybe just a few, mostly on the East Coast, survive... maybe. If we're lucky, regional state-led government transportation organizations take over those lines. If that latter thing is the way this goes, it might actually save money while keeping the most-important lines (again, there are very few of those) open, but at the cost of jobs and transportation options (despite their sucking, those lines do see riders, often but not always low-income and/or retired) in places outside the Northeast, and largely "red" states.
