Main Street Bail Out

How do you bail out Main Street? And how would such a  Taxpayer bail out get repaid?

 In all the other recent Bail Outs, the Taxpayers   got repaid ( in whole or for the most part) by those who were Bailed Out.

The  Big Banks repaid all of their Bail Outs, with a $40 Billion profit to the Taxpayers. AIG repaid it's Bail Out, with a sizable profit to the Taxpayers as well. Even the Auto Companies repaid most of their Bail Out funds.

In all of these Bail Outs the recipients gave the government stock, warrants , other collateral, or otherwise  promised  to  repay the Bail Out. They did  repay their Bail Outs, and in the case of the Big Banks in a relatively short time .

How would we Bail Out Main Street?  What kind of collateral would the government receive?  And once the Taxpayers did Bail Out Main Street, how would the Taxpayers get repaid?

I'm not trying to be cute or facetious. I just would like to know the answers to these questions because  the question of why Main Street has not been Bailed Out has become such a mainstay of our  political discourse.
