After World War II the glorification of an ever-larger GNP formed the basis of a new materialism, which became a sacred obligation for all Japanese governments, businesses and trade unions. Anyone who mentioned the undesirable by-products of rapid economic growth was treated as a heretic. Consequently, everything possible was done to make conditions easy for the manufacturers. Few dared question the wisdom of discharging untreated waste into the nearest water body or untreated smoke into the atmosphere. This silence was maintained by union leaders as well as by most of the country’s radicals; except for a few isolated voices, no one protested. An insistence on treatment of the various effluents would have necessitated expenditures on treatment equipment that in turn would have given rise to higher operating costs. Obviously, this would have meant higher prices for Japanese goods, and ultimately fewer sales and lower industrial growth and GNP.
