Modern “capitalists” like to use the markets choice of ‘better price’ to seek out value, while possibly ignoring other issues that may be as important in price when considering the purchase of an item. The reason something may be cheaper, may be because it actually is not cheaper. Its just different people are paying for it, rather than the end consumer.
Best example of this is ‘Free Healthcare’. It’s ‘Free’, can’t get much cheaper than that. TINSTAAFL. There is no such thing as a free lunch. Someone is paying for it. As in health care, it goes with many ‘Cheap Foods’. This is why a salad costs more than a Big Mac. Federal and State intervention into the markets through subsidies, monopolies through regulation and other state tactics.
My uncle had a dairy farm. The ag rep would come out and ask what he was going to grow on some acreage. Uncle, who studied hard, would reply with some crop he knew was flooding the market. Ag rep would pay him NOT to grow the crop.
