To show y'all that I'm not just a crazy pie-in-the-sky philosopher, I'll now propose 2 ideas for product.
1. Authorized Credit/Debit Card -- cannot be used while stolen. Why? Because it is authenticated by phone every time it is used. 2 options. a) allow a pre-emptive text message from a defined number to specify the $ value of the next purchase. b) send text messages to given # upon purchase, require confirmation.
2. Replace many/all welfare programs with said authorized credit card, or thumbprint-card. $1k/month. If there's money in the card at the end of the month, pay full month. If none, pay 1 week at a time. Virtues: makes marginally more difficult off-the-books (drug) transactions. Allows analysis of spending patterns for real, so as to improve the program. Could permit targetted prohibition (can't use in liquor stores). With above, avoids (most) theft problems.
