Well food prices are significantly lower in the EU than the US. A more dramatic case, Spain, the consumer bread prices can be 1/10 US prices. Vegetables run a fraction of US price, eggs about 1/3. Even corn is less expensive when it reaches the consumer. Yet the median wage is on the order of .75 US and minimum wage including farm worker wages, are higher.
Yet US agriculture is more mechanized and agro-business more consolidated and the country significantly more efficient. So empirically the most significant factor is now something else.
