As well, you should also take into consideration, what the 2016 inflation adjusted debt accrued by Reagan, Bush 1 and Bush 2 is. They added a combined total debt of $9. 263 trillion in "nominal" dollars at the time it was incurred. 

In inflation adjusted dollars, Reagan's, $1.86 trillion added to the debt in nominal dollars, now equals aprox. $4.6 trillion in 2016 inflation adjusted dollars.

In inflation adjusted dollars, Bush 1's, $1.554 trillion added to the debt in nominal dollars, now equals aprox. $2.7 trillion in 2016 inflation adjusted dollars.
