Those examples you mention are pretty insignificant compared to the global warming crisis we are experiencing now. Reading history won’t really help, because we have never faced what we have faced now in human history: manmade global warming in an industrialised, highly specialised society.
That is silly logic.
Also the past 50 years has not been all improvement, the global warming crisis has steadily grown worse to name the most obvious. The economic crisis following the results of that global warming is also just going to get worse. This will lead to more political crises as politics will get steadily radicalised and authoritarian.
