Do you have to pay taxes on dividend under American law ? If so I guess that makes stock buyback better from a point of view of shareholders

You pay taxes in Dividends, which is one reason shareholders generally don't like them. A lot of shareholders are also in the savings phase of their life - they are working some other job and don't need the income from Dividends yet and so getting a dividend is a bad thing as it is more money they have to invest (particularly if you have to pay for each trade which is common). Shareholders who are retired like dividends because it is a simple paycheck without needing to sell their shares and they would be paying those taxes anyway.
