Wolf, I like this topic and think I need to mull this over.
Here is what I would do off the top of my head:
1) Sort of do the Village (by M. Night…) – Buy Iowa and move all frum people there (assuming they dont/cant move to Israel)
2) Reimplement a farming society – this would make Jews self sufficient. We would have a complete system – wheat (and other grains), fruits/veggies, dairy (which would be 100% chalav yisrael because its all frum Jews doing it), cattle etc. People would be getting excersize (being healthy), have pride in being self sufficient…all of this would be done with Jewish labor – no hiring others. We all have to contribute!
3) Establish a rotating learning schedule – except during harvest season, all men would have 1-2 days of just learning while others worked in the field and partial day learning other days.
4) Abolish money. This is a utopian society and we all help each other for the good of society, not for personal gain.
5) Abolish the current shidduch system (no more table cloth questions!). Reinstitute Tu B’Av.
6) Establish a school system without segregation. The school system will be rub based on learning styles rather than religious levels. Kids will be placed where the learning style works best FOR THEM, not whats best for the parents or shidduchim or anything else.
Ok this isnt a well thought out plan yet, but its a start 🙂
