High rate of compression

For my next feat, in a single haiku I will summarise the United States of America, Singapore, Timor Leste, and many other countries around the world. Here we go:


Inequitable
Socioeconomic
Stratification


I realise this is a real brain twister, so I will elaborate each word into its own haiku:


Inequitable

Unfair or partial:
Of treatments, situations
In society


Socioeconomic

About matters of
Wealth, income, and resulting
Structure or order


Stratification

I refer here to
The distinct separation
Of social classes
