A July 2009 World Bank report shows that anti-dumping, safeguard and other trade barriers are currently in vogue, despite the fact that state leaders vowed at the London G20 summit not to do so in the wake of the global economic crisis. The report warns that the present year-to-date pace of new safeguard investigations is likely to make 2009 the second most prolific year since the WTO's inception in 1995. Not surprisingly, the surge in domestic protectionist pressures stems from the negative impacts of free trade on income disparity, as evidenced by worsening inequality in about two-thirds of the countries between 1990 and 2005. Rising impoverishment alongside burgeoning largesse of the already rich, poses a major threat to global social harmony.

Free trade is essential for maximization of global economic welfare, rewarding "factors of production" according to their productivity, thus allowing nations and individuals to exploit respective "comparative advantages". Free trade also frees individuals from the shackles of local tyranny, tradition and provincialism. Globalization is a sine qua non for free trade, promoting benefits that are ubiquitous, compelling, and incontrovertible. Globally, a stunning 135 million people escaped dire poverty between 1999 and 2004; this being more than the population of Japan or Russia, with favorable impact on more people, more quickly, than at any other time in history.

Although developing countries' income levels have been catching up with rich countries in this globalization era, the problem is that income disparity is widening within nations and between individuals. Within-country income distribution has become worse virtually everywhere. In China, for instance, urban-to-rural household per capita income in 2004 was 3.2 times, and the coastal-to-inland GDP per capita was 2.4 times; these differentials being amongst the highest in the world. Moreover, China is but a microcosm of increasing global income disparities. For instance, over the past decade, inequality has increased in 13 out of 18 Asian countries.
