Yes, everybody has their pet programs they like to see from government, but it is disingenuous to consider all such programs equal in merit or equal in value.
Moreover, not everyone places the same value on the same programs. Even the services I tend to want from government I don't value highly for the most part (although keeping the bad guys on the other side of the border is definitely valuable and important).
Which is why the level of taxation is the problem. The notion that taxes can be raised to fund everybody's spending desires is irrational and bereft of any economic legitimacy. Only by keeping taxes low and pushing them ever lower can truly difficult choices between guns and butter get made. Only by keeping taxes low and pushing taxes lower can real debate on the real value of government-provided services get started. Setting taxation levels to cover every program desired by anybody (or at least any Democrat) prevents any and all considerations of value, and thus makes choosing completely impossible.
