Often attributed to Abraham Lincoln, it was actually an introduction by William J. H. Boetcker in his 1942 work Lincoln On Limitations.  Many readers wrongly assumed these statements were also from Lincoln.  However the lack of a deceased presidential attribution doesn’t make the statements any less true.

You cannot strengthen the weak by weakening the strong
You cannot help the poor man by destroying the rich.
You cannot further the brotherhood of man by inciting class hatred.
You cannot build character and courage by taking away man’s initiative and independence.
You cannot help small men by tearing down big men.
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 establish security on borrowed money.
You cannot help men permanently by doing for them what they will not do for themselves.
