The position of Auto Czar is interesting. Obama is coming up with all sorts of executive positions to determine who gets what money. George Will and others have pointed out that this is patently unconstitutional. Congress appropriates tax funds, not the executive branch. Congress can't just rubber-stamp a bill that allows an Obama appointee to hand out money.
This is but a rational conclusion of decades upon decades of government expansion. In a government that takes care of approving new medicine, regulating children's toys, drugs, the Internet, new electronic, bailing out banks, education, urban development, model rocketry, guns, dog food, protected species, national parks and monuments, border security, a two-million-man army, anti-discrimination statutes, health care for the elderly, the postal service, interstate highways, driver's licensing, and several dozen issues, it is not possible for either the legislature or the voting public to keep reasonably informed about all of these issues.
The solution, if you have a government that big, is to appoint executive officers (that's 'bureaucrats' in non-euphemised English) and delegate the daily management of such issues to them. To some extent this is remedied by earmarks – which are corrupting, but at least they are administered by a democratic process - but in general this is the irresistible trend of a government this size. Look at Europe. They have hordes of bureaucrats for this very reason.
Now, one could argue that this is not what the Founders meant – but then, how many people care about that, these days?
