No, I am dramatically understating the value of the average person from 10,000 years ago not the other way around.<p>Child care for example has actual value which is part of current US GDP.  A bow, tent, or clothing constructed using methods from 10,000 years ago has real world value today. But, I am calling all that 0 and just looking at food.<p>Also, this is per capita GDP, having more people does not mean peoples standards of living automatically increases.<p>PS: The common cold was not an issue back then as the population was to low to spread it around.  In fact a large chunk of diseases only showed up as population density increased.
