Having received healthcare services in countries with socialized healthcare, no it doesn’t look like that at all.

Have you ever going through airport customs in Europe and compared it to the US? Sure, other places can do these things well, but the US doesn't have a track record of competent government services.

I hear USPS worked phenomenally well until it became a political target. I think the issue is less that we can’t and more that we won’t support or improve these systems for ideological reasons.

USPS is a sanctioned monopoly with a USO.

It's illegal to compete with it.

It's like saying AT&T "worked". Sure you could buy a phone service and pay $$$$ for it, but if I had a better way of running it, they would put me in jail for trying.

The monopoly is only over mail and is scarcely enforced nowadays. And yet USPS is still cheaper and better on parcels where it doesn't have a monopoly, so much so that private parcel delivery will often just use USPS.
