Spending on education&#x2F;tuition is how middle-class Americans ensure the lower class ones stay down there. If spending on schooling was capped the way most things are capped then there would be much more competition for &#x27;white-collar&#x27; jobs.<p>eg. middle class families may spend a little more on food on average but they are not going to spend &#x27;beyond their means&#x27; on lavish cuisine in the hope that it will ensure a health advantage, because it obviously won&#x27;t. The same is largely true of the quality of education available - there&#x27;s no reason why the outcome (actual learning) should get much better by spending excessively on it. But then you have to factor in the signalling and filtering aspects.
