Absolute nonsense. Much of Africa has life expectancy in the 40s. Capitalist Swaziland has a life expectancy of 39.6 Are you trying to claim it would be impossible to increase these figures?6.7 billion people live in the world.
The death rate is 0.9 per year.
This means 60 million people die each year.
Therefore, you believe that in the absence of capitalism, 10 million people would die each year. A death rate of 0.15.
A 0.9% death rate implies a 67-year life expectancy in the present day.
This means you believe that in the absence of capitalism, humans would on average live for 402 years.
