There was considerable economic growth during Rafael Trujillo's long and iron-fisted regime, although a great deal of the wealth was taken by the dictator and other regime elements. There was progress in healthcare, education, and transportation, with the building of hospitals, clinics, schools, roads, and harbors. Trujillo also carried out an important housing construction program, and instituted a pension plan. He finally negotiated an undisputed border with Haiti in 1935, and achieved the end of the 50-year customs agreement in 1941, instead of 1956. He made the country debt-free in 1947. This was accompanied by absolute repression and the copious use of murder, torture, and terrorist methods against the opposition. It has been estimated that Trujillo's tyrannical rule was responsible for the death of more than 50,000 Dominicans.
