TANF and SNAP are very different than what I am discussing. That are wealth transfers from general taxes to those in need. Very different than wanking into a public grocery store and seeing different prices based on your income.

Where I am, most grocery stores have two prices for items on the shelves. One "regular" price, and a second, lower price that only applies if one is paying with SNAP.

Feels like we're splitting hairs a bit here.

Maybe, I have never seen such dual prices. Are they state mandated?

I guess im still looking for some limiting principle. Why not just mandate that all goods are sold proportional to income.

What are you so afraid of?

That taken to an extreme, this idea is the same as "from everyone according to their ability, to everyone according to their needs". Which sounds great, until you realize that this incentivizes needs and disincentivizes abilities.

Which really is just a manifestation of "when a metric becomes a target, it ceases to be a useful metric".

There are ways to disentangle the undesirable incentives. The Nordic countries in particular have done a great job of this.

Inability to work and create for my own benefit and that of my family. Collectivization and theft of my labor value.
