Tax policies matter, no matter what the Left says

Here's a funny limerick, from LIMERICKS ÉCONOMIQUES by Dr. Goose (whoever he is):
"The $37 Billion Question"

The $37 Billion Question 

Said a Harvard professor of econ,
"That Google's got something unique on:
They have cash by the score,
Yet still borrow more;
This is something I've puzzled all week on." 

Said an expert in cross-border taxes,
"I should hope the professor relaxes;
As Google keeps cash
In an overseas stash,
'Til taxation here wanes and not waxes."

Why does that limerick amuse me? Because it shows that tax policies matter. Google recently borrowed $3 billion. My first reaction: Why the hell does Google need to borrow money when they have approximately $37 billion in cash? Research the issue a bit and see if effective tax rates in different countries didn't play a role. A big role.
