I know there are tons of old outlets in the US which are two prong, but has anyone seen any new US constructions (or renovations) using two prong?

My bigger concern is how many three prong outlets in older constructions there are in the US where the grounding wire is not properly hooked up, e.g. where the home owner just swapped the outlet and didn't rewire?

PS: While we are on the topic of schlocky wiring, did you know that with a little practice you can plug a two pin continental European plug into a UK power outlet? I'm sure the BSA would go nuts, but it is easy to do.
