Kasha,
You are being highly disingenuous when you cite Rambam in support of universal full time learning. Here is what he actually said about it (Hilchot Talmud Torah 3:10):
“Anyone who decides to be engaged in Torah [study] and not to work, and will be supported by Tzedaqa – this person desecrates God’s name (*Chillel et Hashem*), degrades the Torah, extinguishes the light of our faith, brings evil upon himself and forfeits life in *Olam haBa* (The world to come); since it is forbidden to derive benefit from the words of Torah in this world. The Rabbis said (Avot 4:5): Anyone who derives benefit from the words of Torah in this world, forfeits his life in Olam haBa. They further commanded and said: (Avot 4:5) Do not make them [the words of Torah] a crown to magnify yourself or an axe with which to chop. They further commanded, saying: (Avot 1:10) Love work and despise positions of power (*Rabbanut*). And: (Avot 2:2) Any Torah which is not accompanied by work will eventually be nullified and will lead to sin. Ultimately, such a person will steal from others. “
