here's the basic problem with...all political positions, more or less. let's say that you have some really good ideas about how the future should be. and let's leave out of consideration your fallibility, and just stipulate that these are, really, good ideas. it's a further assertion, and does not follow trivially, that you should seize and wield political power sufficient to realize these goals. and whether the idea with all the mechanisms needed to enforce it is still a good idea is an open question. education is good and important, and is basically to be articulated in a no child left behind kind of way. this is wrong. but say it was obviously right. now would it follow that you should not allow high school dropouts to drive? or that you should triple taxes and invest them in schools? or that you should remove truants from their families? well, no. not at all: a thousand other considerations, policies, values, budgets are engaged.
now partly this is a matter of figuring out what the priorities are among competing agendas, or the effectiveness or cost/benefit or unforeseen consequences, of a particular policy. but it also raises fundamental matters of value: to what extent does implementing this idea compromise freedom or whatever else you might value? what does it imply about power relations in the culture? if you thought that essentially no policy passes this test - that the power required to implement an idea was never sufficiently justified by the outcome, then you'd be an anarchist. for example, since every implementation of every policy legitimates power inequalities and expands them, you might think no political program could be justified.
but it's also a basic problem within mainstream politics: you just nod along going: health care, energy independence, environment, education. but what resources are necessary and to what extent are these in competition? and what powers are you consituting and what might be done with them in...the palin administration?
