Corporations got Reagan to construct the regulatory environment conducive to the globalization of production. This allowed Walmart to get over 50% of its products manufactured in Communist China. It allowed Nike to get it's sneakers made in Taiwanese sweatshops. Reliance upon ultra cheap labor markets in freedom hating, dictator-lead nations allowed corporations to radically lower their labor costs and increase their profits.
As corporations began to get more and more of their labor and raw material from unstable or hostile parts of the developing world, the military budget skyrocketed. This meant that the taxpayer began subsidizing the "military extraction" costs of corporations. The PC term is "stabilization". (Military protection of private sector supply chains is called welfare capitalism, which happens when business captures government and privatizes public resources. The story of American capitalism is the story of big business special interests which capture the state)
Two important things happened when production was globalized.
1) Corporations and their investors made unprecedented profits.
2) Americans lost good jobs/benefits and began to rely increasingly upon credit (debt) to stat afloat.
Essentially, Reaganomics ushered in the transition from wage-based consumption to debt-based consumption. Starting in 1980, American families began to borrow like never before. This transition to debt-based consumption actually resulted in a boom in the 80s and 90s.
The problem with funding consumption with debt (e.g., credit cards, personal loans) is that it only works for so long. Eventually, too many consumers become financially insolvent; they reach a point where they cannot consume and they cannot borrow another dime. When this happens, consumer demand shrinks to the point where the capitalist has to start laying workers off. This results in fewer consumers, which, in turn, results in more layoffs. It's a toxic cycle.
