I am starting to add up the flows in and out of the "real economy", which is represented by the line between consumers and enterprises in my diagram of suckage.
Out -> Principal and interest payments on:
Home mortgages
Home equity lines of credit
Revolving consumer debt
Non-revolving consumer debt
Commerical mortgages
Corporate bonds
C&I loans
In <- New borrowing
New home loans (but not existing, because that typically just swaps one loan for another)
Mortgage equity withdrawal
Credit card balance increases
New non-revolving loans
New commercial loans
New bond offerings
C&I balance increases
The main money flows in the economy.
