Western leaders today are the worst our countries have ever had.
The clowns in the 1930s weren’t that great
Arguably things weren’t that good around 1912.
The 18th century also had a few problems.
I think that today and the lot around at the time of Versailles would be close to a wash.
Though I will say many of the leaders did a better job of leading in the sense of going somewhere with vigor—the destinations were somewhat ill-conceived.
Ours look worse in someways because they are inheriting a legacy that has already chewed through a great deal of social capital.
I agree that the non stop wars of yesteryear were atrocious and that people live far better today, but at least leaders of the past were EDUCATED, whereas today they live in a fog of utopianism. IMHO, our Founders got the formula right as to how to build a humane and wealthy country. The tragedy is that so few of our “leaders” today fight to preserve that.
