I've been invited to give feedback to all Parsons students, regarding your thesis projects.
I think you've done a terrific job of identifying a problem and offering a systemic solution. It's true that consumerism is on the rise and impacting a whole generation of youth in terms of fiscal responsibility.
Your solution to this problem is refreshingly creative. With Stashbox and Cache Card, you've considered a 3D savings account as well as a card that will reflect back to youth and teens their spending patterns. Both ends of cash flow (input and output) are represented, which helps to paint the big picture in a cyclical fashion.
Most interestingly, you have an ultimate goal of educating early on how to be financially responsible. This reflects a long-term approach, which has a better chance of bringing about systemic change. For the greater good.
Very well done. Good luck with bringing it to fruition! J.
