You do realize companies that provide those valuable goods can grow faster, hire more people, and grow our economy's GDP much quicker, with more capital, correct?
No. Not correct at all. There is no evidence whatever showing that the current size of the financial industry caused faster growth, more hiring or GDP growth other than the financial industry itself.
And since we're on the subject of evidence - what do you think of this:
The private goods-producing sector value added fell 6.4 percent in 2009, after a 4.2 percent decline in 2008.
The private services-producing sector declined by 2.1 percent, after a 0.4 percent increase in 2008.
The finance and insurance industry grew 6.1 percent in 2009, partially offsetting the widespread economic decline. The increase was primarily driven by the strong recovery of the insurance carriers industry.
