Never trust a businessman

"The proposal of any new law or regulation of commerce which comes from [the business community] ought always to be listened to with great precaution, and ought never to be adopted till after having been long and carefully examined, not only with the most scrupulous, but with the most suspicious attention. It comes from an order of men, whose interest is never exactly the same with that of the public, who have generally an interest to deceive and even to oppress the public, and who accordingly have, upon many occasions, both deceived and oppressed it."   --Adam Smith

Lucretius on Sisyphus and public office

"Sisyphus too exists before our eyes in real life.  He is the man who thirsts to run for the rods and cruel axes of public office, and who always returns beaten and dejected.  For to pursue the empty and unattainable goal of power, and in its pursuit to endure unremittingly hard toil, that is the struggle of pushing uphill a stone which, in spite of all, at the very peak rolls back and hurtles downward to the level ground below."   --Lucretius 3.966-1023
