Malachi 12
Biblical prophetRelated quotes

“You cannot lift the wage earner up by pulling the wage payer down.”
Actually a statement by William J. H. Boetcker known as "The Ten Cannots" (1916), this has often been misattributed to Lincoln since 1942 when a leaflet containing quotes by both men was published.

Context: You cannot bring about prosperity by discouraging thrift. You cannot strengthen the weak by weakening the strong. You cannot help small men by tearing down big men. You cannot help the poor by destroying the rich. You cannot lift the wage earner by pulling down the wage payer. You cannot keep out of trouble by spending more than your income. You cannot further the brotherhood of man by inciting class hatreds. You cannot establish security on borrowed money. You cannot build character and courage by taking away a man's initiative and independence. You cannot help men permanently by doing for them what they could and should do for themselves.
