The uniting concept in the Leftist economic program is the politically controlled Cartel — whether in health care or energy or finance. Cartels force the consumer to pay higher prices for a lower quality product. They force workers and suppliers to do more for less. They exist, in short, for the benefit of those who control the Cartel. In this case that is bureaucrats, technocrats, politicians and their cronies.
Of course they do not promote these Cartels by announcing the real purpose. Instead they tell you it will save lives or money or the entire planet. Salesmanship is important — especially when selling lemons.
