From day one we should have put the money into effectively isolating the elderly and high risk. Most people aged 60-85ish live at home alone or as a couple, so that would’ve been easy to do. For the ones that lived with family, we should’ve spent the money on hotels for isolation - this would’ve also kept the hotel industry going. Without the youngish and healthy sat at home, the food delivery slots would’ve freed up for the elderly, so that wouldn’t have been the issue it was.
The rest of the population should’ve worked from home where possible, but the gyms, hairdressers, shops etc should’ve stayed open for them to use. Of course masks, hand gel, distancing etc would still be in place, but the number of businesses that have closed is tragic.
As for schools, they should’ve stayed open all along, but lessons conducted in marquees outdoors, or in the schools halls etc so distancing could be maintained with the windows wide open.
