Could the NHS be fully privatised after the General Election, and would that be a good thing?

I have heard that several parties are considering this, ad we've already heard Farage and a couple of Tory MPs suggest its time. Cameron famously privatised Royal Mail in 2013 even though many said it wouldnt happen.

So is this something we'll see after the election? How do you feel about having to buy insurance? Would taxes be lowered?

OK. Bit shocked this got so downvoted. How can we ever learn unless we play devil's advocate and try to look at all sides? So I ask again, could there be benefits to this and what would those be? Apart from a few people making a quick buck there must be something in this or else the public would make more noise?
