It's all about when it was done. Before the GFC everyone believed that if you were rich you were smart and the opposite. If you challenged this you were a loser.

Then along came a cranky old uncle, who had no business being in the building, except that he did.

Turns out he had a point and now we consider these ideas trivial.

Today if you say all people are born equal and deserve equal rights 99% of the world will agree. There was a time when this wasn't true.

What you say + when you say it = what it's worth
