Money is fungible, but the word "subsidy" does imply a flow of government to someone. Tax break is the proper term to use unless you are deliberately trying to mislead people. See also "corporate welfare".
I've commented on this before in other threads. There's a (rather disturbing IMHO) school of thought that thinks government is the ultimate economic engine. Thus any money the government doesn't collect is equivalent to subsidy.
The banks are sitting on something like three houses for every homeless man, woman, and child in America, refusing to drop their prices to market level.
Can I see a citation for that statistic please? Or at least your calculations to come up with that figure?
