Farage's so called plans to sort the NHS include cutting tax and giving all NHS workers a tax free income. And giving a tax break to people who use private healthcare.
Clearly Farage is not a stupid man. He doesn't actually believe that you can run a health service on very little money. He just thinks voters are stupid.
The European insurance based systems all cost a lot more per head than the NHS. They spend a third more than us, at least. Why does Farage think it would be cheaper here? If anything it would cost more due to the poverty and health inequality that is so much worse here than elsewhere (more people on benefits, addicted, obese etc)
The immigration issue is so bad partly because the Tories didn't staff the departments properly leading to 2 year delays in cases being heard. This is the cause of the need for housing them in hotels, barracks etc. Apart from that the UK takes far fewer asylum seekers than other European countries. Most asylum seekers stay near their country of origin. Then some stay in other European countries. Only a small minority make it as far as the uk. This problem is constantly misrepresented by the press. The existence of asylum seekers is largely due to western foreign policy.
