A wealth gap is an economic difference between classes.
The term “wealth gap” refers to the gap in wealth between two groups such as rich and poor people.
Usually, research on social inequality points to the difference in income to compare social groups. For example, when they say that the richest 1% account for 1/3 of the world's income while the poorest 50% concentrate only 12% (according to economist Tommas Pickety).
However, the term wealth gap makes the comparison by the optics of total wealth, and not just income. This form seems to be more effective, since it receives all the patrimony of the people, including the real estate patrimony.
