Idioms and Phrases with money talks
Wealth has great influence, as in Big contributors to campaigns are generally rewarded with important posts—in politics money talks. The idea behind this idiom was stated by Euripides in the fifth century b.c., and some 2,000 years later Erasmus spoke of “the talking power of money” (Adagia, 1532). The precise current locution, however, only began to be used about 1900.
