The books that touches exactly that ideas are amongst other

* "Capital in the Twenty-First Century" - Thomas Piketty

* "The Spirit Level" - Wilkinson & Pickett

* "The Price of Inequality" - Joseph Stiglitz

However, at this point I wouldn't be surprised if none of these authors ring a bell.

But is seems like you are perfectly able to articulate the ideas - just not to internalize them. Yet.

How is Cuba doing with all that equality?

Maybe read: "Free To Choose" - Milton Friedman ?

I never proposed any single way to achieve equality.

Even Friedman also agrees with the ideas that I propose: Friedman believes in a basic safety net that ensures that you have basic necessities.

The key as that your secured income is big enough that you can pay for a roof, food and clothes.

My point is that this alone puts a upper bound to the amount of inequality you can have.
