>A staggering 30,000 scientists
According to the US Department of Labor, as of 2012 (all scientific and engineering fields within the US are growing at a steady rate, so it would be higher today) there were an estimated 6.2 million scientists and engineers (legitimate scientists and engineers, as opposed to political scientists, landscapers, and park rangers) working in the US alone.
It would be impossible to give an accurate estimate on just how many scientists and engineers there are worldwide, because scientists and engineers are considered assets to most, if not all nations. Some countries are not at all open about just how many they have at their disposal. Even a free, and open nations like the US are bound to have quite a number of them who are not at liberty to discuss their careers, period, due to national security concerns. In places like Iran and North Korea, scientists are at best kept on very short leashes, and at worse held against their will and never see the light of day. It is probably worth noting that the US population makes up a measly 4.35% of the entire human population though, and that scientific and engineering related professions account for 4.8% of the US workforce.
I'll tell you what though, I'm going to be extremely conservative and generous here, and pretend that there are no scientists or engineers outside of the US. None. 6.2 million are all that exist as far as we are concerned here and now. 30000 is 0.48% of 6.2 million--less than half of 1%. Your alleged 30,000 "scientists" is a fucking joke, and completely trivial.
I thought Capitalism was supposed to be wonderful, and above all question or scrutiny. Are you, and this John Coleman fellow commies or something?
