It doesn't matter how many government housing projects that began with lofty rhetoric and heady visions have ended with these expensive projects being demolished with explosives, in the wake of social catastrophes that made these places unlivable.
To those with the crusading mentality, failure only means that they should try, try again -- at other people's expense, including not only the taxpayers but also those who lives have been disrupted, or even made miserable and dangerous, by previous bright ideas of third parties who pay no price for being wrong.
This headstrong dogmatism and grab for power is not confined to housing. Attorney General Holder is also taking legal action against the state of Louisiana for having so many charter schools, on grounds that these schools do not mix and match the races the way that public schools are supposed to.
The fact that those charter schools which are successful in educating low-income and minority students that the public schools fail to educate are giving these youngsters a shot at a decent life that they are not likely to get elsewhere does not deter the ideological crusaders.
Nor does it deter the politicians who are serving the interests of the teachers' unions, who see public schools as places to provide jobs for their members, even if that means a poor education and poor prospects in life for generations of minority students.
All this ideological self-indulgence and cynical political activity is washed down with lofty rhetoric about "compassion," "inclusion" and the like.
