I too would be interested to know what approach you took with your assignment.
The most obvious answers that come to mind in terms of "finance for better society" are financial planning perhaps becoming standardized and mandatory curriculum in schools. Only a small percentage of people bother with financial planning in terms of preparing for retirement, knowing how to plan for their future or be ready for events such as economic recessions. Better financial planning could make a huge positive difference in peoples lives.
Investment in stocks, bonds or precious metals could also be a mandatory course in schools. Some degree of economic curriculum might also be mandatory to ensure that students have a decent comprehension of economic implications in terms of political issues like healthcare, taxes and other subjects which would help them to understand the nature of issues surrounding controversial things like healthcare, foreign wars, economic stimulus, bank bailouts, et al.
Any financial or economic topic covered in school could benefit from attempts at real world application. There isn't much application in terms of real history nor encouraging students to think about things in their own terms independently. A lot of education is heavy handed and might be described moreso as indoctrination rather than real knowledge or education.
Thanks to your well answer. (But too late for submit your thinks in my homework.)
If got me thinking here, about you topic. I see no one put interest but me can you share you homework with here this would be very helpful. If you thinking I might copy it no I want to know some details here.
I already give it to my teacher. I don't have a photo about that.
