Druckenmiller also spoke about the credit crisis, expressing concern that corporate debt has ballooned faster than corporate profits and interest costs. He pegged corporate debt at $6 trillion in 2010 and $10 trillion now, while corporate profits grew from $1.7 trillion to $2.2 trillion cumulatively over eight years on a $4 trillion increase in debt. Additionally, he notes that while debt increased 65%, interest costs only went up 23%. He described this situation as “horrendous productivity of capital.”
