Sweden remains a social welfare society, and government spending still accounts for half of its economy; it finances all education and health care, as is common throughout Europe. Sweden did not dismantle the social system but, in addition to drastically reducing its costs, adopted macroeconomic and structural reforms to make it sustainable and greatly enhanced its efficiency by privatizing the delivery of many educational and medical services.
