We see in post 6, that an over-debt monetary, system is vulnerable to financial crisis-es, e.g. by sudden increase and decrease of oil prices.
Now over-debt exists in all levels of the economic system
a) In the public sector
b) In enterprises
c) In the households

But the households are the more vulnerable, as they do not have organised ability for profits as enterprises do, neither large inertia and resources as a public sector does.
Therefore the weakest over-debt link would be the debts of the household. Now the main debt of the household is the real-estate loans. Indeed the financial crisis of 2008 started with the securitized home-loans.
