CONSIDER in real-world:
    * moving > $250k into say ING, then rabo-bank -- 4 months interest higher in each -- maybe to another provider after that
        while the balance is > $250k it offsets individual bank risk
    * maybe buying shares in something like berkshire-hathaway, or vanguard ETFs?
    * pay out car if the diff is negligible to reduce the exposure to > $250k in bank

To run the code:

cd ~/src/finplan
source ./.python/bin/activate
FLASK_APP=main ./.python/bin/flask --debug run --host=mara.ddp.net
