One reason that keeps the cost of meat from being any higher than it already is is the almost exclusive employment of cheap labor by illegal immigrants in slaughterhouses and meat packing plants. Notice that Trump hasn't cleared these places of illegal immigrants, which would raise the price of meat substantially.
I noticed the phrase in the article, "the watchful eye of the USDA". The USDA only spot-checks meat in the slaughterhouses anymore, and the task of meat inspection has fallen upon the illegal alien employees. Meat inspection by laymen can be learned and somewhat adequately performed. However, employment by illegal aliens is so tenuous that if they start rejecting too much meat, then their employment and even their right to live in this country are in jeopardy.
