Have you ever had a friend who offered you constructive advice?It usually begins something like this, "If I were you, I'd go for the salad." Or, "You know, if it were me, I wouldn't be spending so much, but saving more."Yet here's the kicker: The person offering the food advice was fat and the person offering the financial advice didn't have a proverbial pot to you-know-what in!That's the trouble with constructive critics, they don't practice what they preach. And that's the trouble with the government.Its books are crooked as all heck, but now it's offering corporations advice on their books. Its bureaucrats live off the fat of the land, but now tell us how to eat. It's crazy. And it's dangerous. The government telling us what not to eat. The government telling companies what not to do.I've said it before, I'll say it again: I won't offer you dietary advice nor should you take it. So, Uncle Sam, don't offer me ethics advice, because none of us want it. The government has roles to play -- playing a hypocrite isn't one of them.All the corporations we have caught and the CEOs we have collared happened without a new federal agency that's now law. You can't legislate decency any more than you can legislate healthy eating.Those in power want more power to keep us from getting greedy and from getting fat.But some will still be greedy. And a lot will still be fat. But all will be under the thumb of a government that has gotten greedier and fatter on us.What do you think? Send your comments to: firstname.lastname@example.org.
