Harlan F. Stone,
New York ex rel. Cohn v. Graves…
“ A tax measured by the net income of residents is an equitable method of distributing the burdens of government among those who are privileged to enjoy its benefits. The tax, which is apportioned to the ability of the taxpayer to pay it, is founded upon the protection afforded by the state to the recipient of the income in his person, in his right to receive the income and in his enjoyment of it when received. ”
