My generation received ZERO instruction on how to manage money. Zero. I did fine. Everyone I went to high school with did fine. Managing money well only requires that one spend and save no more than what one earns. Make good choices with your money. Simple. Whinge-ing is in fashion.
The same for me. I did an economics course at high school (more at university) but it had nothing to do with personal finances.
And rewarded with social points that have no value.
