You are describing the situation often occuring in poverty, crime, and violence plagued communities (of which the US has many). In those situations schools need more funding than a more well off area because they are doing more than education: they are default community social support centers, providing food, mental health support, and sometimes even shelter for children who are facing horrible scenarios in their communities and homes.
Pulling funding from those schools without addressing the societal issues will make things worse, not better. Right now, the school is the point of social service delivery.
