I am beyond "done" with listening to what people think they should or should not be expected to do in a world-wide health crisis like this.
My parents were young adults during the Second World War. The UK and every Allied country gave up so very much for the war effort. Food shortages, bombardment, lives lost in battle, everyone pitched in. Because not doing so would mean losing everything. The USA, we did our part too, though not suffering as much as your country did.
So now, with hundreds of thousands of lives already lost, and more on the line, is it asking too much to put on a mask, stay 6 feet apart, and take a jab in the arm when it becomes available??
John, I quite agree with what you say about medical costs in the USA. I have insurance through my work, it does not cover everything, I have to pay a lot for the employees part of the insurance, with any medical care I have beyond check-ups I must pay several thousand dollars before insurance pays anything. I have saved responsibly and well for a retirement that I have not reached yet. I think my family is better prepared than 95% of my countrymen for retirement, emergencies, etc. Despite this, one difficult or prolonged illness (COVID, cancer, etc.) is all it will take to wipe my family out financially.
So yes, if I were in the UK, I think it would be quite reasonable to say, take the jab or be locked out of NHS.
