You are deliberately pulling my chain lol
You must get it by now that S&D works regardless if there are good or bad social outcomes. When the outcomes are bad that's when regulations and laws are needed so S&D will produce positive social outcomes.
Blaming S&D for worker exploitation is like blaming gravity for plane crashes. When was the last time a plane crash investigation determined the cause of the crash was gravity? There's a lot more going on that causes the plane crash than the constant of gravity.
