The world as a whole – definitely. Our personal spiritual heights, no that’s what this thread is about…
But yes the physicality of this world is much more refined.
Like in your examples:
The time of Shlomo hamelech is compared to the time of moshiach,as all the nations were at peace with us, but the fiend is that then the nations were temporarily overwhelmed by the kedusha emanating from eretz Yisrael, but still remained the same evil nations, and so it didn’t last.
Now however, the nations themselves are allot more refined, they admire chessed more than brute strength etc, and some are already serving Hashem.
When moshiach comes he will finish it off with “Az ehpoch el hoamim safa brura likro *kulam* bshem Hashem.” Bimheira vyameinu amen!
