I quite like that idea.

If you receive a dollar and pay tax on it due to the work you undertook to receive it, it gets 'refreshed' and increases in value.

If you get a 'stale dollar' (e.g. gifted from a parent) it depreciates until you use it constructively.

If you're an advocate of "trickle-down" economics, you should be lapping this us, as it's rewarding people for what you believe already happens.

Of course a much simpler approach would be to simply flip the outrageously stupid system most of us have, where income from passive investments is taxed at a lower rate than income from providing work.
