I understand how it works, and I am comfortable with my criticism of that post. Dismissing criticisms of "what the world is" allows the bad parts to flourish. The status quo does not capes.
We get how this works. You say you don't condone his wretched behaviour, but keep writing these "aphorisms" and sound bites which imply that "you can't do much about it". The bad parts will flourish if you let them.
The fundamental point remains: do your damn best to be decent to other humans; don't make excuses.
There are plenty of businesspeople in my circle at least who are decent people who wouldn't dream of doing this to a partner or even an employee. As an owner of a small business I include myself in that group. Being an asshole isn't "business" - it's just being an asshole.
If the most important thing to you is not to be decent to others, you live poorly.
