A significant portion of 'white' gear appliance equipment, made and sold in North America, does not meet any basic stuff in CISPR14.2, but agree that most of the ITE/AV/industrial stuff has been tested and certified per the EMC or RTTE directives.
Should be noted that some of the appliance safety standards indirectly require immunity. The expectation of a North American-based global corporation to self-regulate is not unreasonable. My employer is a supplier to several F500 companies, and their level of product control and testing indicates that they are interested in both controlling costs and controlling product reliability. Where most large western companies lose control in their pursuit of the bottom line is at their Asian or Latin American factories where any number of unknown shenanigans routinely occur. A good design does not always survive the factory... Per the OP, the few products with a USB port were taken to a MS461 lab where RS/CS gurus live. They have saved our bacon more than once (mmm, bacon).

When Wall Street analysts expect public companies to show higher profits quarter after quarter, lowering the cost becomes the key driver. However most US companies ship their products overseas, and almost all of these countries have some form of immunity requirements, similar to the EU regulations. Hence one can assume that the products built in US are designed to meet these requirements. The sad thing is that in until the eighties US was leading the world on EMC requirements, but now has fallen behind. My personal view.
