The most intellectually dishonest argument against universal / socialized healthcare is "wait times".
Dude, I pay $2k/mo for healthcare and am lucky if I can get a video appointment in the same week, much less an actual, physical appointment.
Our ERs and urgent care centers are chock full because folks can't get easy, inexpensive appointments, so they let things go until they become an emergency.
There's no way universal healthcare makes that worse.
