Of course I can't predict what will happen but it's very clear that less money always means less money. A lot of businesses rely on bank loans to make ends meet with regards to payroll. This might not apply to Dell but it applies to a lot of small business owners who need the extra help until they get paid by their clients and then pay off the short term loan. Stricter payroll loan policies (when money is scarce = bank reaching low levels of liquidity) puts businesses in tough situations leading to sudden layoffs.
The Fed's goal is to try and regain control of the system (they lost control last summer). So by tapering they're shaking the tree. Just like you'd put an electrical signal through a black box and study the output in an attempt to understand how it works, the Fed is gradually cutting its $85bn per month supply of "cash."
That's what the Fed (Yellen) is doing right now. I'm sure they'll react if things degenerate too much.
FYI, it's a carnage in the financial markets right now. Dow was down several hundred points in Jan. Several hundred points just today.
1) More layoffs in different sectors of the economy
2) Less VC funds to go around
3) Main street feeling the brunt of it
