The whole premise of MO was that traditional Orthodoxy would become no more than a museum piece unless he reformed/modernized Orthodoxy.
B”H, the Orthodox world (i.e. non-MO) has, of course, not needed MO’s reforms to Hashem’s Torah; while Jews of all stripes face financial struggles, there are still successful businesses that are owned, and run by, and that employ, chassidim, besides for the traditional Orthodox who also run businesses or are otherwise employed in various fields of work, whether white-collar or otherwise.
Rabbi JB Soloveitchik clearly stated he was deviating from his family tradition in the matter of Zionism. Yet the senseless and idolatrous worship of Zionism is one of the major mitzos of MO. They observe Israeli nationalist holidays as religious observances, etc.
Put simply: Even without the (rather major) Zionism issue, MO is a mistaken ideology that is kineged our Torah. We are already seeing the initial stages of disintegration of MO (as prominent MO writers have been decrying for years now); those leaning “to the left” become, CH”V, Conservative or worse, while those leaning “to the right” become traditionally Orthodox, B”H.
