It is very hard to separate the effects of any particular cause when everything else is changing a lot.
Of course it may well be that Hayek- inspired Reagan's and Thatcher's reversal of Keynesian "central planning/spending" economic policies were the major factor in the incredible growth of US and British economies in the late 80s and through the 90s, continuing today.
But at the same time technology changed drastically. Computers became commonplace, many other technologies too that caused productivity increases. How does anyone ever separate the effects?
midnight Target: Reagan spent us into a debt that was unprecedented in history.
That is a liberal mantra exploiting the common american ignorance about financial matters - and based on the fact that US does not track current and capital spending separately.
Everyone knows how much debt increased in Reagan's years. Nobody asks how much our net worth increased in the same years.
When I bought a house, I spent my family into a debt that was unprecedented in history (of my family, et least). But did my net worth really change? Not a bit. I owed money to the bank but I own the house worth the same amount.
While my financial situation did not really change with the purchase of a house and assuming a huge debt, the house did allow me to expand my family (added a dog and a baby), grow a lot of vegetables in my back yard, open a home business for my wife and improve our quality of life significantly.
If you just look at my liabilities and ignore my assets, your picture will be very far from reality.
Many private companies carry a lot of debt but nobody worries untill that debt exeeds their capital assets. That's why they borrow money - in order to buy capital assets, expand and grow. Without borrowing there would hardly be any growth in private sector.
During Reagan's years our debt did grow. But most of it was spent on what should be classified as capital improvements. Our assets - roads, briges, airports, other infrastructure, military hardware, etc. grew too. And most of those were helpfull in ensuring the productivity growth of the following decades.
