Smart companies do. Dumb ones do not.
However, with the current bunch of economic illiterates running congress and the white house, why would anyone start or expand a business in this country?
And of course, inevitably when the SHTF, the managers responsible for the offshoring are long gone, and it's up to some other poor sap to clean up the mess.
In my experiences regarding offshoring, it is driven by corporate bean-counters trying to lower short-term costs. Period.
Myopic corporate beancounters (and Wall Street bankers) are merely "useful idiots" for long-term marxist planners like Blinder.
You are too myopic in your perspective. I do not doubt your observations and decision making time horizons. These policies have major impacts on short-term costs. The immediate impacts of these laws are often difficult to measure. The long term impact will be unmistakenable however. The Lilly Ledbetter law is a good example. Over time, litigation associated with this law and new regulations and practices necessary to comply with the law and avoid litigation will have a major impact on hiring and retention of good talent. Corporate decision makers will take notice and move work to locations without these restrictions.
