We know that there is no such thing as truly 'menial' in this world.
But Haredim, like all other Israeli Jews, indeed like all Jews everywhere, won't sweep streets or clean stair wells no matter what, as it's 'beneath their
kovod'. The breed of Sefardi Jewish Yemin Moshe washerwoman immigrant from Tunisia cleaning on her knees has gone forever, as has the old
"Jewish work ethic" that R.Kahane so extolled.
What's considered a "menial" job? And why would people refuse to do a job that would sustain them and their families?
It is part of Hashem's plan that the Haredi populace now start to self limit, as their 10-15-20 children per family is finacially untenable for the new generation, being that the Haredim although nominally Torah observant, are
80% unworthy, still support "Land for Peace" in principle, are strongly anti-Kahanist, anti-Hill Top Youth and anti-Chaim:
"The Haredim are IRRELEVANT!" (R.Kahane 1980), is still true today, and it will always be so!
