I'm not saying it is, and I'm not entirely sure about the credibility of conspiracies, but does anyone think that this virus was manufactured, or more specifically, do we have the means to manufacture something like this? If the answer to the second question is yes, then I propose the answer to the first question might also be yes.
Why you might ask? Because it's the quickest and cleanest way to reduce the population. I could go into a conspiracy rant here, and generally I laugh at them (especially ones revolving around the earth being flat, and the royal family being reptilian aliens etc) but if this viral outbreak was intentional, it would ... make sense.
It's no secret that there's a lot of people on this little blue planet, and our numbers (up until 2020 at least) have been increasing. It's only a matter of time before there's too many of us, and not enough of the planet and it's respective resources.
It would be unethical to impose child tax, or a means by where families were limited to one or two children per (how do you even police that?); didn't China even try that a few years ago? Obviously it didn't last long. If there's one way to reduce a population it's through a viral outbreak that targets the old and vulnerable, and it would only need a small number of skilled people behind it to make it happen.
Again, I'm not saying this is the case, would such a thing be possible if we wanted it to be, and then if such is possible, why couldn't that actually be happening?
