The post-War suburban sprawl in North America was made
possible in part by technological changes that supported mass
production of the private automobile, and mass communications
(phone, TV and radio). But the technological changes would not
have been possible without the extremely high rate of capital
accumulation in North America and around the globe, and its
concentration in the North.
It made possible a national
interstate highway system and mortgage insurance programs that
subsidized suburbanization to the tune of billions of dollars.
This suburbanization was not possible in Latin America
because of the net outflow of capital from the region.
As a
result, the economic surplus available to the masses did not
permit anything approaching the mass consumption
This made possible the growth in mass
consumption associated with "the American dream" the single
family home and private auto.
