While local businessmen have historically tended towards more upstanding behavior (possibly because having to deal with your neighbors directly, after screwing them, does not lend itself to a long or prosperous life), the largest business institutions have almost always held to the rule that they are allowed to do whatever they are allowed to do, and more to the point, they are also allowed to do all the things they are not allowed to do so long as they don't get caught. Or so long as the repercussions for doing so are less significant than the profits to be made.
What seems to have happened of late is that more of that behavior has, for perhaps obvious reasons, shifted into the political sphere. Political figures who seem to care honestly about helping their communities, as opposed to ones merely willing to pay lip service to the premise, are more often considered sentimentalists or rubes. There used to at least be the rosy premise that some of the people seeking to lead government would be in it to make America a better place, but the definition of better place now consists almost entirely of what the same captains of finance and industry (a.k.a., the crooks, as per above) believe would make it better. It isn't just notions of caring for the poor and the sick that are now scoffed at as socialistic functions of government; even re-paving community roads is met with skepticism and hostility. And in Congress, the standard of behavior has steadily declined from the level of what should be done to what is the lowest level that can be gotten away with.
