S&P 500 revenues are running at $10.5T/yr. while their retained earnings are running at about $150B/yr.
This savings rate is less than half of the EU treaty targets of 3%.
So the firms are somehow getting it done well within the "debt to GDP!" limit most of the morons seem to be triggered by which seems to be around let's say the 3% point.
The problem for these morons has to be coming from other segments of the system other than firms.
