It’s a fact that many rich countries – rich in terms of total GDP – have a substantially unequal distribution of income; or, to put it in other words, these countries accept that there is huge inequality of wealth between people. It’s also a fact that, in many countries and particularly the U.S., these inequalities in income or wealth have become wider over the last decades.
What’s the problem, you may ask. Well, according to me this inequality poses some problems. But these problems are of relative importance. More important to me is the problem of absolute poverty. Absolute poverty is a lack of certain resources that are necessary to meet certain basic needs. This is not a problem of inequality. People may live in a very unequal society and at the wrong end of inequality, but they may nevertheless have no problem whatsoever meeting their basic needs.
More important as well, in some aspects at least, are the problems posed by other types of inequality. Gender inequality in some countries may be much more of a problem than income inequality (although these different types of inequality are probably connected).
Nevertheless, income inequality engenders some important problems. One is self-esteem. People suffering from relative poverty – i.e. finding themselves on the wrong end of an unequal income distribution – may suffer psychologically and emotionally. It’s also likely that their relative disadvantage isn’t very fair. In other words, it’s probably not solely based on questions of merit and desert. We don’t live in a world of equality of opportunity and level starting conditions. There’s also a correlation between relative and absolute poverty, so we may have to worry about relative poverty as a cause of absolute poverty.
Income inequality can also cause a problem for democracy. The rich can use their financial means to pervert the democratic procedures and to distort the equal influence on which democracy is based. Another way in which income inequality may pervert democracy is its divisiveness. It polarizes societies and it can antagonize regions within countries. None of this is helpful for the adequate functioning of democracy.
