Comprehensive, as in extensively but not necessarily totally? And why as a species rather than as countries, given we don't have a single world government?
Equality issues still exist, but compared to 1924?
Is literacy is a social issue or not? 31% to 87%.
Is extreme poverty? 54% of about 2 billion, now 10% of about 8 billion, reduced in absolute numbers and not just as a percentage.
We haven't. Even simple ones like poverty, hunger, homelessness that are just a matter of admin and money. We've been captured by self-perpetuating and effectively immortal institutions (NGO's and arguably governments) that will not let us solve them because that would mean their own death.
I agree with the spirit of your argument but maybe not the villains you've chosen. Given legislative capture is absolutely a thing I think your criticism is more effectively pointed at the individuals and organizations responsible for funding reelection campaigns for the politicians that aren't obviously servicing the needs of their notional constituency.
