and Denmark. With a few exceptions—France, Japan, Spain—the top 10 percent of earners in most advanced economies raced ahead, while the bottom 10 percent fell further behind. By 2013, 85 multibillionaires had amassed wealth equivalent to all the wealth owned by the poorest half (3.5 billion) of the world's total population of 7 billion. Critics of globalization argue that globalization results in weak labor unions: the surplus in cheap labor coupled with an ever-growing number of companies in transition weakened labor unions in high-cost areas. Unions become less effective and workers their enthusiasm for unions when membership begins to decline. They also cite an increase in the exploitation of child labor: countries with weak protections for children are vulnerable to infestation by rogue companies and criminal gangs who exploit them. Examples include quarrying, salvage, and farm work as well as trafficking, bondage, forced labor, prostitution and pornography. Women often participate in the workforce in precarious work, including export-oriented employment. Evidence suggests that while globalization has expanded women's access to employment, the long-term goal of transforming gender inequalities remains unmet and appears unattainable without regulation of capital and a reorientation and expansion of the state's role in funding public goods and providing a social safety net. Furthermore, the intersectionality of gender, race, class, and more remain overlooked when assessing the impact of globalization. In 2016, a study published by the IMF posited that neoliberalism, the ideological backbone of contemporary globalized capitalism, has been "oversold", with the benefits of neoliberal policies being "fairly difficult to establish when looking at a broad group of countries" and the costs, most significantly higher income inequality within nations, "hurt the level and sustainability of growth." Anti-global governance Beginning in the 1930s, opposition arose to the idea of a world government, as advocated by organizations such as the World Federalist Movement (WFM). Those who oppose global governance typically do so on objections that the idea is unfeasible, inevitably oppressive, or simply unnecessary. In general, these opponents are wary of the concentration of power or wealth that such governance might represent. Such reasoning dates back to the founding of the League of Nations and, later, the United Nations. Environmentalist opposition Environmentalism is a broad philosophy, ideology and social movement regarding concerns for environmental conservation and improvement of the health of the environment. Environmentalist concerns with globalization include issues such as global warming, global water supply and water crises,
