"One of the things I did take seriously when I was in law school was taxes," Cramer said Monday on "Squawk on the Street." "The main thing you learn is that tax avoidance is everybody's … duty. You're supposed to try to avoid."
Cramer made his remarks after Apple's chief executive called the notion of the company dodging taxes on overseas profits "political crap."
"Apple pays every tax dollar we owe," Cook said Sunday on the CBS program "60 Minutes."
"There's confusion between the words 'avoid' and 'evade.' 'Avoid' is patriotic because you're allowed to figure out the code," Cramer said. "'Evade' [and] you go to jail."
