Why doesn't a single politician ever really talk about how much money we all need to make to survive decently. [View all]

The number in my head for Urban America seems about $75K per year after taxes.

My whole point in bringing this up is to ask why we don't uniformly address our true poverty and the hidden poverty that exists all over the USA?

I am not an economist, so any answer to what income needs to be before we start taxing it as the taxation itself is reducing the primary driver of our economy, Consumption.

I hope someone smarter than me can explain why something like that wouldn't work?
