Sure we can craft policy that way! It's just a matter of wisdom and desire.
If you have a policy/program to address a concern and people aren't signing up for it, I would say the reasonable options are to accept that some eligible people don't want/need it, (2) try to increase awareness of/enrollment in the program, or (3) redesign or scrap it and come up with something new that people will take advantage of. It doesn't seem reasonable to add redundant programs or to avoid other policy decisions because of a lack of enrollment.
I dont think it does reinforce your point, though I'll admit this discussion is spinning me around right now as i am not as versed in translating rightie crap theory into reality on this topic as on others, and ive only glanced at the link. It says SNAP users do not make decisions based on price, which makes sense as they don't see the price anyway.
Correct. That was one of my points. The ones who are the worst off don't have to pay much of the tax (only on their non-snap spending).
It says the poor that don't use SNAP are sensitive to price, and will alter purchasing based on tax.
This is one of my other points. People that are better off but not well off will adjust. So they have some control over how much they pay, but at the end of the day they have to buy groceries so they will pay the tax (and at the end of the day, somebody has to pay tax). And as you note in your last sentence, the study says well off buyers don't seem to adjust at all. This is good. It means they pay more tax and don't engage in any wasteful tax avoidance. So the poorest aren't taxed, the slightly better off are but have at least some control to limit the tax (although it will involve some deadweight loss), and the well off will pay the most and will not engage in any wasteful tax avoidance activities or will create relatively little deadweight loss. And as you noted earlier, the exception to all of the above would be people that are eligible for SNAP that don't utilize it.
So, these people are presumably purchasing cheaper, less healthy food due to the current tax.
I would say probably not. People aren't generally making tradeoffs between price and healthiness. They are making tradeoffs between price and convenience and taste. Some of the changes people make in response to price will push them to less healthy alternatives, some will push them to healthier alternatives. I don't know of anything that would indicate which direction that would go on net. People like to pretend that eating healthy is a cost issue, because then there is an easy solution, but that's just not the case. If you go to the grocery store in a poor area, you mostly don't see people loading up on food that is cheaper than dried beans, in season fruits and vegetables, brown rice, etc. In fact, it's not doable politically because of the strength of certain food and beverage companies, but I think you actually could get people to eat healthier if you made soda and high carb, low fiber/protein (e.g., chips, cookies, etc) ineligible for SNAP and relaxed the ban on hot food for beans and vegetables and rotisserie chicken.
And guess who pays their future med bills? This is a classic dead weight loss, which we could remove by eliminating this tax.
That is not a dead weight loss. Arguably it's an externality if you make certain assumptions.
Then the not-poor are not price sensitive, so there is no dead weight loss there as they buy what they buy regardless. Eliminating this tax on them and replacing it with another may create dead weight loss, or may reduce it if the new tax is well crafted.
