services such as electricity and healthcare. In most developed countries, local or national governments continue to provide such services, the biggest exceptions being the U.S. and the UK, where private provision is arguably proportionally more significant. Nonetheless, such privately provided public services are often strongly regulated, for example (in the US) by Public Utility Commissions. In developing countries, public services tend to be much less well developed. For example, water services might only be available to the wealthy middle class. For political reasons, the service is often subsidized, which reduces the finance potentially available for expansion to poorer communities. The United Nations Sustainable Development Goal 5 is however, a global initiative which aims to influence the provision of public services and infrastructure to marginalized demographics. Nationalization, privatization and personalization Nationalization Nationalization took off following the World Wars of the first half of the twentieth century. In parts of Europe, central planning was implemented in the belief that it would make production more efficient. Many public services, especially electricity, fossil fuels and public transport are products of this era. Following the Second World War, many countries also began to implement universal health care and expanded education under the funding and guidance of the state. Privatization There are several ways to privatize public services. A free-market corporation may be established and sold to private investors, relinquishing government control altogether. Thus it becomes a private (not public) service. Another option, used in the Nordic countries, is to establish a corporation, but keep ownership or voting power essentially in the hands of the government. For example, the Finnish state owned 49% of Kemira until 2007, the rest being owned by private investors. A 49% share did not make it a "government enterprise", but it meant that all other investors together would have to oppose the state's opinion in order to overturn the state's decisions in the shareholder's meeting. A regulated corporation can also acquire permits on the agreement that they fulfill certain public service duties. When a private corporation runs a natural monopoly, then the corporation is typically heavily regulated, to prevent abuse of monopoly power. Lastly, the government can buy the service on the free market. In many countries, medication is provided in this manner: the government reimburses part of the price of the medication. Also, bus traffic, electricity, healthcare and waste management are privatized in this way. One recent innovation, used in
