How to kill a country's education system

Give teachers tenure, so bad ones can't be fired.
Make better students study longer so they spend their prime years off the workforce and delay compounding job skills.
Make the same institutions responsible for both education and certification introducing a massive conflict of interest.
Mandate all degrees have the same length so that even people studying simpler degrees graduate with large debts and huge opportunity costs.
Hire teachers based on qualities other than how good they are at teaching – for example, how good they are at writing papers.
Have the government, not colleges, loan money to students so universities have no skin in the game of their students.
Forbid students to use tools they will have access to for the rest of their lives, such as Excel or AI, so that they don’t learn how to use them.
Only publish research beyond paywalls, especially research that used public funds.
Group everyone by birth year regardless of talent, so that the smartest students slow down to the pace of the slowest students.
In general, design an education system around the assumptions that knowledge is scarce and student time is abundant, in an age where the opposite is true.
