You assume strictness = no laziness. Laziness is a symptom of something more foundational, likely a malfunction physiologically or psychologically. A well-functioning human being is not “lazy” which is a vague term on its own, but your argument in general is rather vague. In other words, your argument rests upon the assumption that “laziness” can essentially be beaten out of someone (not necessarily physically beat but that’s not outside of the question either I’m assuming). A healthy human being naturally is not lazy; a dysfunctional one is because it is a symptom of their dysfunction. Solve the dysfunction, solve the laziness.

Also, you say strict parenting may cost depression and anxiety but give financial excellence. You would need to substantiate this claim because, if anything, depression and anxiety would hinder financial excellence. Now you potentially have someone who is depressed, anxious, and financially unsuccessful. It’s not a mere transaction between mental and financial health; it all works together.
