I am not Capitalist minded enough to understand the motivation, so am curious if maybe it will only be a short lived fad or forever. YKWIM? I am afraid to make any longterm plans and I don't want to go back to working in a large center, again. 
It's forever, because real college educated teachers have unions. They can't take jobs away from them when they have tenure. They can't just leave a building vacant once they build the prek. Where I live, it took three years from a neighboring district to go no prek to full day prek for 3 and 4 year olds.
