I think these two example are to the point. They're really the only outsized debts that most people have that aren't just "generally need more money". They should be tackled separately in addition to general wealth distribution policies.

> If a large percentage of the population can't participate, the market's capability to price, evaluate and represent value is hindered.

Note, that the actors having roughly proportional buying power is also important. Having actors that control disproportionate amounts of wealth also hinders the market's capability to price. We need explicit measures against wealth accumulation if we wish to have functioning markets.
