A researcher trying to find ways to keep black bears away from humans once summed up the problem for me with a simple calculation: Animals are driven to obtain the maximum number of calories for the least amount of effort, and people leaving high-calorie food out attract the bears.
The same drive applies to executives and profits. Executives seek to maximize returns, for the least amount of effort. And American tax laws benefiting foreign-owned multinationals encourage them to merge with foreign companies and move offshore, a process called a tax inversion.
Expecting anything else, really, is going against nature.
