In life, some teenagers when they go to university, or move out from the parents' house or start an apprenticeship or job, suddenly they panic as they don't know how to pay rent, or they don't know how to control their spening habits. In my opinion, when students start secondary school, one of their lessons per week should be about financial aspects of life.
These financial lessons would include how debit and credit cards work, how to save money and how to pay rent or mortgage. Some people (young people especially) don't know what to do if they don't have much money. People take out loans, thinking 'Oh, I can pay that loan in a few weeks!'- a few weeks later and before you know it they take out more and more mony until their debt is out of control. What if teenagers are orphans or live on their own? Who would teach them about how to handle money when they're older? This is why I think we should have financial lessons.
One of the reasons why the Fianancial Crisis of 2008 happened were that people took out loans they couldn't pay back, causing havoc throughout the country. If we had financial lessons in school (and I know I would like to have them) then everyone would be more aware of the financial aspects in life and this could prevent another possible financial crisis.
