He is simply more important by virtue of being the PM
A chronically underfunded NHS will struggle to offer everything that could be offered to patients if better funded. This is not a slur on the NHS staff, it's a criticism of the politicians who make funding decisions and those who voted for them
So, in conclusion, BoJo got preferential treatment, this is not necessarily immoral in itself, but what is problematic is that decades of underfunding mean that treatment that is available in other countries will not be available on the NHS (equally treatment that is available on the NHS won't be available in many, many different other countries). The average COVID patient will not get early intervention because the NHS simply can't do it
The NHS simply can't do it because of decisions taken by the party currently led by the man who gets preferential treatment. The party that brayed like disgusting fools when they blocked pay rises for public services.
Whilst I agree with the sentiment of what you have said I simply do not agree that Boris should have received preferential treatment. Whilst his role may be considered to be more important than that of other workers he, as a person, his life is no more important or valued than any of the other 10000+ who have died or the thousands more who will die. He is nothing special at all. He is a lying, self-serving adulterer. He is not a man I would be proud to have as a family member.
The precautionary treatment he received should be available to everyone. Perhaps with the magic £350m it will be when the next pandemic comes around (pigs may also fly).
It so is political. And I agree with those that say he has flouted isolation rules. His flat at 11 Downing Street is where he was living before this - he popped back to Downing Street to make his speech. He should have stayed there. It is not the equivalent of living at the office. Carrie Symonds should not have gone to Downing Street to meet him, especially not accompanied by two security(?) personnel in the car - does social distancing not apply to these people? She was previously at their own home or Chequers. She should have stayed there. They are not love's young dream, far from it. The rest of us can't visit other households, the rest of us can't see loved ones, the rest of us have to have our weddings cancelled and no-one attend our funerals. But these two are ferried around the country. Hypocrites.
