The most important word in all this is panic.
We are in Austria and have been in lockdown for a week. Supermarkerts are open and with the exception of a few specific items (loo roll of course) there is no shortage of food.
I went to my supermarket down the road and it was almost empty of people but well-stocked.
I am not saying the politicians here are perfect but the way it has been handled was so much better.
Schools were closed incrementally, starting with the older kids who wouldn't need childcare. All schools are open for parents who can't WFH (not just key workers) but DS's school has only 5 kids attending (3 from the same family where both parents are doctors). Nurseries were the last thing to close and again, are open to anyone who can't WFH.
We got a week's notice of the first closures and 10 days of the closures for kids up to age 14. The last 2 days were made voluntary so people could keep kids home if they could but people weren't screwed.
Of course people here are going to lose jobs and it is a shitty situation, but there have been no false promises, no U turns, no dropping things on us at the last minute. We are only 1 week into a 4 week lockdown and we are already being told to prepare for it to be longer. I feel I am informed, that there is a plan, and we are privy to it. The UK has easier borders to control (we border 7 countries here) and had more notice of what was coming than most European countries.
Britain has been divided for the last 4 years with Brexit and this crisis is deepening the divisions and the feeling of 'otherness' about people not in your circle.
It is the government's job to give confidence and gain trust. There is no trust in the UK that the government or anyone else will look after you, hence the panic.
BoJo needs to gain the trust of the people to calm the fear which is causing most of the current problems.
With so many disbelieving every word he says after Brexit, he has an uphill battle.
Personally, I don't think he is the man for the job but he is who you've got so I am really hoping he has hidden depths.
