While I can't deny the argument that US national anti-TB efforts have become fragmented, possibly as a result of lower incidence, BCG isn't an especially protective vaccine against pulmonary disease and can interfere with TB skin testing, which even in this age of generally available blood QuantiFERON testing is still not uncommon. BCG does have greater value in high-risk countries, and it may be most useful for kids in those regions where TB meningitis is a bigger threat. It doesn't make a lot of sense in a low-burden country, but perhaps one day we'll have a better one. - working in TB control since 2006
