Every ideology and system is fundamentally flawed.
Worse, zealots (of said I/S) compulsively refuse to recognize that their own house needs cleaning. And they not only don't clean, they'll savagely attack anyone who attempts to do the needed cleaning (improve the ideology by addressing it's flaws).
No One Anywhere Will Clean Their Own House is an absolute human constant, right between death and taxes.
