"As a dog returneth to his vomit..." Why plans for making people happier/the world better - inevitably go nowhere

 As a dog returneth to his vomit, so a fool returneth to his folly. 

Proverbs 26:11. 

Every day our speech and writing, our conversations and media; the world of academia, medicine, officialdom, news and education... are such all replete with analysis, reforms and strategies for making the world "a better place", or making some class of people happier, or less miserable - or whatever...

Oh so many "good intentions" from so many directions, and unrelenting. 

Yet it all adds-up to a Great-Big Nothing-Burger...    

Indeed, things overall keep getting worse, the decline being actively fuelled by the endless affected-attempts at betterment.

Why? 

Because our fundamental understanding of the world is false. 

In other words: 

When our basic understanding of the nature of life and the universe is qualitatively-wrong; then no amount of quantitative activity will make a dent in things.

When deep understanding is wrong; then our sense of the purpose and meaning of life will be wrong, feeble... or (mostly) absent. 

Socio-psychological therapy and reform constitutes no more than patterns of evanescent ripples that sweep and swirl across the surface of an oceanic swell. 

When our basic understanding of oceanic reality is that the universe is purposeless, meaningless, and (mostly) dead - then this underpinning assumption is the vomit to which the dog shall inevitably return; again, and again, and again. 

When Men have become such fools as to pretend that they can have purposeful and meaningful mortal lives without anything to underpin this in fundamental and ultimate reality; such folly will always  undercut all and any superficial efforts at betterment.
