Unnecessary. Their predictions about the price of goods is vastly overstated.
Let's use your reference to lettuce, I have seen that one in the media too. What are those workers making? Minimum wage or thereabouts? Let's say it is just 5 bucks an hour just for the sake of arguement. I watched those pickers in some video on tv, they are pretty speedy.. tossing a head of lettuce about one every 2 or 3 seconds. But lets also be generous and say that for this example, they are screwing around.. picking only 1 head every 15 seconds. That would be 240 head of lettuce in an hour. Increasing the price of a head of lettuce by just ONE NICKLE, will mean that the workers could be given a $12 per hour raise.. for a total of around 17 bucks per hour. I know a LOT of Americans who would beat the doors down to get a chance at a job that pays 17 bucks an hour. At the REAL speed at which they pick lettuce, they could give that $12 an hour raise by increasing the cost of a head of lettuce ONE PENNY.

Well, you don't know me but count me in; see my post #29.
Your analyis is very good. It probably comes out to the same estimation that only 2% of the price of a head of lettuce comes from the labor to pick it. The other price is shipping, planting and watering, etc.
