José has been working hard for the past ten years, but most of the wealth he has is the result of inherited properties. erin has also been working hard for the past ten years, but since she is paid the federal minimum wage and also supports her elderly mother, erin is below the federal poverty line. josé and erin demonstrate

José and Erin demonstrate economic inequality.

Explanation:

In a society there must have same opportunities for all citizens. Nevertheless   economic background and the distribution of goods may be perpetuators of economic inequality, for they determine in most cases the opportunities people have and of course their wealth and income in the future, and therefore directly affect development, with some exceptions, be it individual, regional or national.

Economists have stand out for this, saying that if we want to develop an individual, a region or a nation, we must pay attention to two main elements: distribution of wealth and distribution of income, both to measure economic inequality, that means: the disparity in the distribution of goods and income, and with this emphasize that for the economic improvement of a region, an individual or a country there must be special help for those who don't have inherit wealth because those are most likely to earn less and have lower incomes and thus less opportunities than the ones that come from better or richer backgrounds.

In this case, José and Erin both work hard but their backgrounds are radically different. José have inherited properties, which allow him to make more money than Erin, that has no heritage but to support her elderly mother with a federal minimum wage, this leave her with few opportunities to develop.  Therefore they demonstrate economic inequality.

This is not a case of gender gap for the emphasis is not that Erin is a women but that Erin has a federal minimum wage and doesn't have inherited properties, in contrast with José, that he does, and therefore they have different places and opportunities in society, thus is a demonstration of economic inequality not a gender gap case.
