Richard, There is nothing wrong with a NHS...but as my post indicated, "the HUGE unspoken concern, is what do they want to implement with their 'new program' to go with it."
Right now, in this country, the general population does NOT trust what is coming out of Washington, nor the elected people pushing things that infringe on our freedoms. I believe this is evident by the fact that all the front runners allegedly NOT part of the 'establishment politicians'. It seems that BOTH parties promise this and that, but consistently fail to deliver.
You'd think that Obama's presidency favored an agenda that leaned toward socialism....but every time he delivered, including his 'healthcare plan', was a ruse, to funnel the insurance corporations, business under penalty of law...as he did with 'alternative energy sources', and signing an exemption for Monsanto, for any damages resulting from GMO's..while his Ol' Lady is lecturing the people on, eating more 'natural foods'....and so on and so forth.
Trump on the other hand, is full of a lot of vitriolic rhetoric, which SOUNDS like he is identifying with the public, but he is rather short on the details on how to accomplish any of it. So, it would be fair to assume, that even though he claims to favor a single payer healthcare plan, nobody can really tell if there is some other agenda up his sleeve, other than wanting to be president for a personal self indulgence.
Another problem, over here, is that while a NHS SOUNDS like a good deal, the track record isn't too swift on the governments handling of such things, witness the 'healthcare' debacle, run by the government, for our veterans, which has been a national disgrace, inundated with fraud, scandals, cover-ups, and no criminal accountability...The same may be said for Hillary's obvious, and nationally televised, criminal behaviors of influence peddling and paid for preferential treatments to foreign countries, corporations, and politicians through the Clinton Foundation, while she was Secretary of State.
Personally, I think that IF Washington wants at least SOME trust back from the citizens, they are going to HAVE TO act as if there is at least SOME concern for the ways they have let stuff gone by, without accountability or consequences...and quit letting 'politics as usual' be their 'guiding light'!!
