So, in a war of economies, wouldn't the larger economy have advantage over the smaller? China's economy is now larger than the US's.
The only way the US could regain the upper hand is by being more business savvy and trading it's way back to number one. You don't win by throwing in your hand and refusing to play anymore, after the first hand.
Anyway, we have strayed far from the topic.

The study is not worth much, it is not a proper representation of a populace.
It is RT abusing the study - the study itself was useful for what it tried to be.
The question was: Since we have demographic data for the blood donors and since we have demographic data for confirmed cases, we can compare the two groups. If we test blood donors blood, how well then does the numbers translate between the two groups.
In essence the study asked how many cases went unreported for every one that did get reported.
And since the donors are healthier than the general populace, it could have even greater prevalence...
Tell me again what happens when the number of infected is up and the number of deaths stays the same?
We report the prevalence of antibodies to SARS-CoV-2 in a sample of 3,330 people, adjusting for zip code, sex, and race/ethnicity. We also adjust for test performance characteristics using 3 different estimates: (i) the test manufacturer's data, (ii) a sample of 37 positive and 30 negative controls tested at Stanford, and (iii) a combination of both. Results The unadjusted prevalence of antibodies to SARS-CoV-2 in Santa Clara County was 1.5% (exact binomial 95CI 1.11-1.97%), and the population-weighted prevalence was 2.81% (95CI 2.24-3.37%). Under the three scenarios for test performance characteristics, the population prevalence of COVID-19 in Santa Clara ranged from 2.49% (95CI 1.80-3.17%) to 4.16% (2.58-5.70%). These prevalence estimates represent a range between 48,000 and 81,000 people infected in Santa Clara County by early April, 50-85-fold more than the number of confirmed cases. Conclusions The population prevalence of SARS-CoV-2 antibodies in Santa Clara County implies that the infection is much more widespread than indicated by the number of confirmed cases. Population prevalence estimates can now be used to calibrate epidemic and mortality projections.
