Yes, the AIG bonus issue is economically significant, because it sends a message to other businesses that are thinking about getting into bed with the government, that the government will not expect the employees involved to bear any of the suffering. Instead, it is all put on the tax payers. Whether it is right or wrong, it is a significant issue because it sent a message to everyone.
AIG bonuses is in no way economically significant. Why should one person at the top of the company get millions of dollars in bonuses where the rest of the people who work hard for the company get merely a fraction of the amount. The money should be spread around to every employee in the company because thats how the economy will benefit as a whole.
