Will Small Businesses Be Hurt By A Millionaire Surtax?

NPR tries to find small business owners who will be hurt by a tax increase on people making more than $1 million a year:

We wanted to talk to business owners who would be affected. So, NPR requested help from numerous Republican congressional offices, including House and Senate leadership. They were unable to produce a single millionaire job creator for us to interview.
  So we went to the business groups that have been lobbying against the surtax. Again, three days after putting in a request, none of them was able to find someone for us to talk to. A group called the Tax Relief Coalition said the problem was finding someone willing to talk about their personal taxes on national radio.
So next we put a query on Facebook. And several business owners who said they would be affected by the "millionaires surtax" responded.
"It's not in the top 20 things that we think about when we're making a business hire," said Ian Yankwitt, who owns Tortoise Investment Management.

They found a few affected businesses who weren't concerned about the tax increase, but haven't had anyone come forward complaining that is would prevent them from hiring.  Gee, I wonder why?
