Of course the problem of the last three decades is not the “vicissitudes of the marketplace,” but rather deliberate actions by the government to redistribute income from the rest of us to the one percent. This pattern of government action shows up in all areas of government policy.
For example an explicit goal of our trade policy is to put our manufacturing workers in direct competition with low paid workers in the developing world. This has the predicted actual result of driving down the wages of manufacturing workers and less-educated workers more generally. At the same time we deliberately depress their wages we largely protect the most highly paid professionals (eg doctors, lawyers, and dentists) from the same sort of international competition.
The government has strengthened and lengthened patent and copyright monopolies. This allows for absurdities like a treatment with the hepatitis C drug Sovaldi costing $84,000 when the drug would sell on the free market for less than $1,000. There would be no hand-wringing moral dilemmas about treating people with hepatitis C at less than $1,000 per person. If we just had a free market the government would not be putting people behind bars for 16 months for allowing people to download recorded material.
The vicissitudes of the market would also not have bailed out the Wall Street banks, ensuring that many of the top 0.1 percent or 0.01 percent did not lose their fortunes due to their own greed and ineptitude. It also wouldn’t exempt the financial sector from the same sort of taxes imposed on all other industries. And the vicissitudes of the market would not have a Federal Reserve Board that is prepared to raise interest rates in order to keep people from getting jobs and keep workers from having enough bargaining power to get wage increases.
