I installed around 50 of those in a 2 week period about 7 years ago. They were very expensive, and extremely poor products. They did not effectively do any of what they advertised to a competent level. However, the school sounded modern to the PTA when they said they were buying them.
It is not as if research has shown that nutrition in those first years is extremely important. Who wants more of those pesky tall, healthy kids with properly developed brains and internal organs. /s
What are their priorities in life?
Parents are responsible for the child's nutrition. If the parents don't provide, the school should report it to the relevant authorities (CPS, etc.).
Let schools teach: money allocated for education should be spent educating students, not feeding them.
You've come up with an expensive plan that makes everyone miserable.
If the parents can't afford to feed their children then the children may be put into foster homes with parents who can properly take care of them.
Since only a few parents are (criminally) unable to feed their children, their problems are solved at minimal cost. Other students are not affected by misdirected funds paid to institutional food service vendors, school cafeteria services paid the lowest bid to feed school children instead of educating them.
Your bleeding heart shows:
"he kids are separated from their parents " - what kids wants to live with parents that won't feed them? Ans. Only abused kids.
"the parents are miserable because they lost their kids" - Hell, no. They're likely drug addicts, don't care about their kids, or are incapable of doing so. You're doing them a favor.
"taxpayers are miserable because they have to pay for your new imprisonment program" - You needn't imprison the parents; merely put their kids in decent homes.
My plan is less expensive by orders of magnitude than existing "solutions": it provides appropriate care for the few problematic kids w/o paying millions for institutional cafeterias, food workers, food refrigeration and storage, union dues and unnecessary meals for millions of kids. Money intended for education is spent on education instead of ham sandwiches and cheetos.
I don't think it will work out that well, though.
