Three basic parts to this question:
1. Consequences of unequal dist. of income
2. consequences of an unequal dist. of wealth
3. judgment
Therefore, I will answer it in that format.
Note: consequences can be both + and -
Distribution of income
- there will be increased incentive for workers to migrate to countries that offer higher wages for the same job type. This causes a "skills drainage" in the domestic economy, while the foreign economy will benefit from increased inflow of highly skilled workers that have the potential to increase productivity levels within that country, contributing to economic growth.
- Advanced economies generally have higher GNI per capita of $17,200 (made it up, can't remember exact figure) while developing nations have an average GNI per capita of $7,320 (again made it up). This means that labour in developing nations will continue to be exploited by TNC's who desire to increase profitability by utilising cheap labour found in developed nations. Although TNC's may bring increased job opportunities for the host country, inequality in the distribution of income will persist between developed and developing nations, thus adversely impacting on the living standards of workers in the developed countries as they cannot greatly satisfy materialistic demands in contrast to those in developed countries.
etc
Distribution of wealth
- as discussed above, if inequality in the distribution of income persists between economies, individuals in developing nations will not be able to accumulate much wealth and will not be able to liquidate assets that could have been used to generate income and thus satisfy needs and wants. Again, this will mean lower living standards for those individuals, which may lead to the concept of 'poverty traps' as those who cannot generate enough income for themselves will tend to rely on social security and welfare, increasing budget deficits (that most developing nations experience, since not enough workers have high incomes for the gov. to receive huge tax revenues.)
Thus, the negative consequences outweigh the positives.
P.S. answers will vary, many other points can be discussed and I may have inaccurately answered or discussed things cause its night
