the.com/sweetheart deal

A contract whose best clause is who you know, not what it says.

means An arrangement — often business or political — struck on favorable terms because of a close or cozy relationship rather than fair, open competition.

from Straightforward compound: 'sweetheart,' long used for a romantic favorite since the 1500s-1600s, drifted in 20th-century American English toward anything treated with special fondness or favoritism. By the early-to-mid 1900s, 'sweetheart contract' and then 'sweetheart deal' emerged in U.S. labor and business slang for agreements — sometimes between employers and union officials — cut quietly to benefit insiders rather than the people they were supposed to protect. The romance in the name is sarcastic: nobody's actually in love, just cozy.
