We honestly should just replace every single fixed dollar amount in every law with an algebraic formula. It’s ridiculous that we design laws to become dated and require replacement.

Minimum wage should be tied to worker productivity, and wealth tax should be tied to the median personal income, including that of non-working adults. Welfare programs should be tied to regional cost of living. Limits on rent should be tied to changes in regional median income.

We’re already tracking most or all of that data anyway, might as well put it to maximum use.

I’d also like to hear what your idea is. I don’t know of a platform to solicit someone building your device at a price you’ll be wanting to pay, but there are forums to help you learn how to do it yourself if you’re motivated enough.

If it’s cool enough to pique interest, you could try posting the concept in an electronics community and seeing if anyone’s interested in the challenge, or an ideas community and just floating it for people to choose to run with.

It’s also possible the device already exists and someone can suggest an easy option for you
