How much is one life worth?

I have heard in the UK they don't change an accident blackspot if the deaths per year saved are less than the cost of fixing it by 2 million GBP per person. The very soft lockdown in HK has resulted in about 250 fewer deaths from flu than normal. Let's say the economy has suffered 2 billion USD. They don't have soft lockdowns in HK because of flu because the lives of 250 people are not worth 2 billion USD, or 8 million USD per person. USA had approx 60k deaths from flu in 2019. So they don't do a 2 trillion USD lockdown for 60k people. So one person in USA is worth less than 33.33 million USD per person.
