My dad is frugal and always preaches to live within means. However, if you read Rich Dad Poor Dad, you will realise that most of our parents are typical representation of Poor Dad syndrome, who never got over their fears and worse, passed it on to their kids, i.e. to play safe, live within means, dont dream big, take as safe a job as possible.
A rich guy will never teach his kid to save or live within means. They would rather teach their kids to earn more or at least try. And its not even about money alone. Its about life hacks, positive attitude, getting along with people, playing politics, etc etc. Most people live in a bubble and keep reinforcing their viewpoints to an extent that they never question they may be completely wrong. Unless you admit that you have shortcomings, how are you gonna change, improve and make ur kids a better version of u.
If I asked my dad what his shortcomings are , he will go blank for sure

If person is frugal as a principle, I would respect him. But if frugality is at the discretion of the person who has money n power, I wont respect such a person. If a person talks about frugality over a Nike and then spend 100 times the money on a 24 hr wedding, I think its not frugality, its stupid.
And if see the distribution of Indian and my dad's expenses, its more stupidity than frugality as a principle.
