The excerpt for inequality reads:
Questions on economic, social, racial, gender and any other forms of political inequality, or political topics related to such inequalities.
While the excerpt for income-inequality reads:
Use for questions related to income-inequality and its causes, political effects, or potential solutions.
It appears to me that the "income inequality" of income-inequality may be no different than the "economic inequality" of inequality.
If there were a finer line to distinguish between the two tags, there are enough questions of each to keep separate tags; otherwise income-inequality could be made a synonym of inequality.
Are both inequality and income-inequality necessary or should they be merged? (Please include any suggestions for amending the tag excerpts, if separate tags are to be maintained.)
