You made some wild claims that China and the world knew early on about human to human infections of this Corona virus strain. That simply remains untrue or at the very least completely unproven. And just to deflate your communist suspicions, even leading HK virologists who are by wide agreement among the world's leading experts on pandemics like this were not sure in January whether the virus can spread between humans. Only the first actual documented cases demonstrated that this was possible. What happened in China in December is at best very nebulous. You can blame China for that but it's completely speculative that the spread might have been completely contained if China communicated this outbreak earlier.
You sound like you are extremely pissed off and need someone to blame for your economic setback or family inconveniences.
Whenever there is a virus outbreak of this category there are containment procedures. Investigating the virus is the second step. You don't just let it spread around for months before taking action.
The fact remains there were many cases early on and China tried to bury and forget about it. This was deliberate and they had plenty of time to take action.
My economic setback? I'm up and the outbreak has been beneficial for me thus far. But I'm not a simple voice for my account balance, maybe you are, why else assume something like that?
