How long do you honestly believe an employer can sustain a business providing wages insufficient to purchase food to provide the calories necessary to complete the work?

You are attempting to recast the question to looking at median subsistence-rates worldwide. The Walmart workers we are discussing work in communities in the U.S.

Certainly, some folks in the world survive on $1/day. That doesn't work in the U.S.

We know that Walmart wages are insufficient alone, because workers there tell us that they need, for instance, SNAP to feed their kids.

Thus SNAP is, in part, now a subsidy to Walmart.

The point of this discussion is to shine a light on how ignorant the OP's question was. The original question was whether a person could live off $40/day. But that's not what OP really meant was it? What they meant to ask was whether or not a person could live OP's approximate standard of living on $40/day. And the answer to that is obviously not. If you make more than $34k/yr you're in the global 1%. Virtually no one on the planet lives at the OP's standard of living. The question only shows the OP's hubris.

SNAP is a subsidy for every industry that sells products that people on SNAP might purchase. Every dollar not spent on food is another dollar someone might collect in rent, or cell phone service, or clothing. Wal-Mart may benefit greatly from SNAP, but it benefits far more from its customers having more income that they don't have to spend on subsistence than it benefits from its employees being able to accept a lower wage. And of course Wal-Mart accepts SNAP payments from its customers because Wal-Mart sells groceries.

> SNAP is a subsidy for every industry that sells products that people on SNAP might purchase

You're missing my point. SNAP is a direct subsidy to Walmart not because they sell food, but because many of their workers cannot live where they live without being enrolled in SNAP due to the low pay.

SNAP subsidizes Walmart by supplementing workers' paychecks.

It sounds like you are suggesting that wages should be set at a minimum level that is strictly above any government assistance. So if you have a job, you are disqualified from any assistance what so ever, and all the government assistance should be focused on people without jobs, essentially to bring them to that minimum.

That's similar to what welfare was like before welfare reform in 96 https://en.m.wikipedia.org/wiki/Personal_Responsibility_and_...

I understand your point, I was just pointing you to a different perspective. Wal-Mart makes far more money from SNAP recipients as customers than it potentially saves in wages. I personally do not believe SNAP saves Wal-Mart any wages at all.

I'll circle back to the question I asked several levels ago. If SNAP suddenly disappeared, do you believe that would cause Wal-Mart to raise its wages? If not, then your point is moot since it's not saving Wal-Mart any wage costs.

That depends on how big the available labor force with no better offers is, and what the rate is at which people from outside that group move into it; potentially indefinitely, under the right (or very wrong, depending on your perspective) conditions.

I'd be interested in any examples you have.

Unpaid internships?

Well, you got me there so I gave you an upvote. Temporarily bartering labor for skills training is a complexity I hadn't accounted for.

Yeah, a rather extreme example, and of course we hope they are being sufficiently well compensated in experience, though we know that's not always the case.

As another example, there's the people working 70 hour weeks across 3 jobs - no one of those is paying what's necessary to sustain the employee.

Moreover, if you're okay with high turnover, there may be people willing to work for you unsustainably for a time just to lower their burn rate.

Is walmart not proof that the answer to your question is quite a long time?

No, and this is exactly the point I was trying to drive home when I made my original post about over 80% of the all humans living on less than $10/day. When the OP asked if "anyone can live on $40/day" what they really meant was, "Can people live a lifestyle reasonably close to mine on $40/day." The answer to that is obviously not. The question is being asked by someone who is almost certainly in the top 1% of incomes across the globe (which is about $34k/yr). But the real answer is that a person can live incredibly well by global standards on $40/day.
