You're not looking at both sides of the transaction. You say "it's in the company's best interest to pay their labor the minimum amount they can get away with". This is true, if by saying 'the minimum they can get away with' you are considering the costs of turnover and so forth in your analysis.
But, it is also in the best interest of companies to charge as much as they can for their products. So, using a similar analysis as yours, if we don't legislate a "maximum cellphone price", cellphones will keep getting more and more expensive. One company starts charging their customers a bit more so their profit margin is a bit higher, or so they can sell for a bit more and outperform the competition. The competition follows suit. Customers grumble a bit at the higher process, but it ends up as the norm. Repeat until prices are unaffordable for everyone.
You've got to look at both sides in a voluntary transaction.
If one company raises their cell phone price to make more profit, unless they can offer some additional feature or service to justify that, then they make make more margin per unit but lose in the number of units they cell. You say it yourself, prices increase until no one can afford a cell phone. Not to mention that manufacturing costs there go down with new technology, so they can maintain the price while producing cheaper units.

[Just to clarify a bit, you're ignoring differences between the situations. There are more unskilled laborers than are are jobs for them, and this has been true pretty much forever. The supply of these jobs is limited, and the demand high. So you can offer a lower wage and still find people who will take it. Turnover tends to be high in these types of jobs anyway, and retraining is a matter of a current emplyee talking them through the first day, and having them fill out some paperwork. It's minimal turnover cost.
In the cell phone analogy, you've reveresed the roles. The cell phones are abundant, the number of customers is limited. The customers have a choice to find a cheaper phone, just like the companies have a choice to find a cheaper employee. There's no incentive for the company to pay more, when they can get the same work for less. Likewise, in your example, tehre's no reason for the customer to pay more, when they can get the same phone for less. The company won't gain a profit, bnecause sales go down. But that isn't true in the case of labor. There will be a minima that the lowest wages will reach, but it will be well below the current minimum wage.]
So tell me what I've left out that will keep wages from going below the minimum wage?
Again, where's your evidence?
Now, Balrog666 has a decent point: the minimal income for welfare will set a "low point", if you will.
IN your favor, though, the abuses seen in the past regarding wages were before many of the welfane programs started, so it is worth looking into.
ETA:[Just had to say I was incorrect, here.
The poverty line is $22,500.
Minimum wage, for a full-time job (40 hours a week, 52 weeks a year) comes out to $15,080. So minimum wage now means, assuming no other income, you are already getting those welfare benefits. This seems to suggest that the wefare benefits aren't really a stop or competition for wages.]
And employees are not treated as commodities in all situations. To be clear, I was discussing the overall view, not specifics. Yes, in some cases you treat them as commodities, specifically in cost analyses and similar things. But they are NOT treated the same as raw materials, real estate, consumables, or equipment.
