However, this has to be the most ludicrous argument I have ever heard against universal healthcare in its entirety. It is a classic post hoc ergo propter hoc argument and its universally dumb, it goes like this.
The NHS is state run. State run systems pay lower wages and thus recruit from abroad. Terrorists come to work from abroad in the NHS and then do batshit crazy things. Therefore universal healthcare breeds terrorism, ergo, the US cannot have universal healthcare or jihadists will go crazy.
Don't get me wrong here, I think the UK has a lot to learn from insurance based systems around the world. It is inefficiently run precisely because it is a single monopoly producer interest marketplace. It should be freed up. However, arguing that healthcare should be free from the state because it breeds terrorism is.... well.... it's stupid.
