The renewed industrialization, which based itself on both a dogmatic understanding of Marxian economics and a series of autarkic goals, brought major economic problems to Romania, beginning with the effects of the 1973 oil crisis, and worsened by the 1979 energy crisis. The profound neglect of services and decline in quality of life, first manifested when much of the budget was diverted to support an over-sized industry, was made more drastic by the political decision to pay in full the country's external debt (in 1983, this was set at 10 billion United States dollars, of which 4.5 billion was accumulated interest). By March 1989, the debt had been paid in full.
