Textbooks = cartel economics, captive market. Tuition = gatekeeper for a better life, rent-seeking, high barriers to entry. Child care = Labor-intensive, demand > supply, probably high barriers to entry. Health care = Labor-intensive, demand > supply, high barriers to entry, anti-competitive activities enshrined in law. Food = Labor-intensive, high barriers to entry, subsidized (note: not much higher than CPI.) Housing = hugely illiquid, increasing supply / density very difficult, price dominated by other factors (schools, commutes, crime rate) (note: not much higher than CPI, probably because it has as many downs as ups.)
