The government knows this will spike, their objective is that when the highest % of population are infectious, they will only be able to infect a lower number of new cases, as prior to the spike, a % of population will have already have had it and be immune [ if its true they will be immune as noone really knows for sure]. Prior to the spike, the support services will be dealing with lower numbers of cases each week, as of course numbers will be lower than the spike numbers, during this earlier phase. If they try to stop as many as people as possible catching it at an earlier stage then the graph will have lower numbers before the spike but the spike will be far far higher. So they believe workplaces, economy will not have dramatic collapse when spike comes and NHS would less likely be to totally swamped during spike.So, government wants 30% plus of the population to get it quickly as majority of those will be generally younger/fit/healthy, only having mild symptoms. Then when 40% are infectious, they can only pass it on to smaller % of the population. The 40% then in self isolation can have their work covered by the 30% who are immune. They are not particularly bothered about the groups that arent fit younger generally healthy. They will die before the spike as government wants people to catch it earlier & they will also die in the spike as not enough resources for all.
Treatment will be limited for only younger/fit/healthy. In reality, every year, the elderly and those with underlying conditions die from complications after contracting flu.The only difference with flu to this, is normally each year there is a flu jab, which works in varying degrees each year to try to help people in this group. There is no vaccine for this currently, so greater % of this group will die, as greater % of this group will contract it and resources will be far more limited to those in place for normal winter flu.
Thats why Boris had to include his,"many loved ones will die before their time", in his statement. He didnt want to say that to British Public, but he knows their strategy will kill a far greater % of that sector than others who they want to protect moreso, so hes covered himself. Some will say that the planet needs hefty % of its population wiped out thru meteorite strike/nuclear war/illness. A viral pandemic would be a more environmentally long term beneficial event..
