You're talking about disturbing a system with billions of variables by changing a few thousand of them. Almost any such change will have unintended consequences of the same order as the intended effect. For politicians, this is beneficial, since they can be surprised by the consequences, ignore their causes, and advocate new changes to "fix" them. For someone who actually intends to improve things, such as yourself, the fact that poking the economy with a stick is likely to backfire should be cause for concern. :)
