I think the answers depend on the interpretation of the question - with the original post it my interpretation was that you were concerned about the lack of time with Option A (maybe frazzled gave a stronger impression than you meant), so came across like A)Steiner School vs B)More time with you/parents. So I said B.

Your reply highlighted money more - so if it was A)Steiner School vs B)More money in pocket - I would most likely choose A.

So based on the above if had to make a decision I would ignore the money aspect (unless A) would put you into severe financial hardship) - as think kids enjoy the simple things in life anyway and I would quantify the amount of extra time you will need to spend working/thinking about work to go option A (you still need time to go camping etc) - if is small like an hour a day then A) sounds good. Once it gets into multiple hours a day and not seeing kids before bedtime etc then for me then B starts sounding better.
