>Nonsense. What do you imagine will happen automation arrives at farms? The supply of food will increase, and the price will decrease. Same thing for trucking and the volume of goods carried down the world's roadways. The volume of cargo will go up, and the cost to move it will drop. Thats more economic productivity, which means more for all. Simply awesome.
Short sighted and fails to see many pitfalls.
First off, automation will only be available to those who can afford it. IE multinational corporations. Whether that's good or bad is your perspective, but it will spell the end of many small businesses. Many will sell, some will take on bank debt to try to compete under the new "rules" of labor being a one-time fixed cost that you amortize over an amount of years, rather than being able to pay as they go. That, or they'll cut wages even lower than they already are. And that work force was a million people in 2012.
Second, independantly of that, transportation is another industry that's being threatened with being automated away. That's 6.8 million people (3 million truck drivers, people loading, unloading, etc). Not counting independent contractors, owner/operators, which are very prevalent.
So, food is now cheaper, but you've taken away the means for millions and millions of people to actually purchase food.
And you last supposition, the volume of cargo will go up and the price to move it will drop. That's not correct - the cost to ship things doesn't drop as more stuff needs to get shipped, it rises as producers with more and more product to ship bid against one another in an effort to secure access to a limited resource. Gasoline prices stay constant, tire costs are constant, and the trucks themselves are fixed costs - you don't achieve new economies of scale by shipping more and more, you're locked in battle fighting over the same resources as not only your competition in that industry, but with every industry that has goods they want to ship to market. In the short term, that's higher profit margins for transportation companies, but in the longer term, that means they'll need to expand their fleets to capture more of that lost revenue - whose cost will be passed on to us as well.
So. We produce more food. We have far fewer people able to afford it. You lose tons of small/family farms in order to redistribute that income to Wall Street. And shipping prices most certainly rise, not just for foodstuffs, but for anything else that could be shipped on those same trucks as well.
