Those are not comparable other than that the GDP growth you reference IS that trillion dollars you also reference, and then some. It's essentially like switching to buying everything on credit card to keep up the facade to your friends that nothing has changed, in spite of the fact that your business is bankrupt/you lost your job. The GDP will still go up because you are buying things, but that does not change the fact that taking on one trillion dollars in debt or embezzling one trillion dollars from shareholders of your company is a good idea.
