Completely biased book where the author uses statistics as per his whims and fancies. He is a complete narcissist who believes almost everyone is dumb and he is the enlightened one.
It is VERY obvious that if you compare everything on a scale of 60 years, you will see improvement. He is incapable of understanding that we understand that there might be 100% improvement in the world but it should have been 500% and he doesn't want to accept that.
Read only if you want some positivity on a macro level.
Last but not least, I wish he understood inflation and way below standards of poverty level.
