Perhaps you should try some spelling variations:
"wage and widening inequality" » "wage and deepening inequality", "wage and reducing inequality", "wage and rising inequality"
"wage and garding inequality" » "wage and garding's inequality", "wage and earnings inequality", "wage and hardy inequality"
"wage and warning inequality" » "wage and earnings inequality", "wage and learning inequality", "wage and facing inequality"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("wage and garding inequality") OR ((("wage and warning inequality") OR ("wage and widening inequality")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"wage and garding inequality\") or (((\"wage and warning inequality\") OR (\"wage and widening inequality\"))))".
• Removing quotes may allow a broader search: (( wage and garding inequality ) or ((( wage and warning inequality ) OR ( wage and widening inequality )))).
• Adding a wildcard symbol may retrieve word variants: (("wage and garding inequality") or ((("wage and warning inequality") OR ("wage and widening inequality"))))*.
