I would say that the American consumer shares a higger blame than >1%.
It can be said that corporations, aside from reacting to tax policy, are also reacting to the consumer demand for the lowest price.
That is a very reasonable assessment, very accurate about how it plays out. My only quibble? I still give gov almost all the blame, because consumers, just like companies, are often just trying to survive the economic landscape our government has forced on us. And often consumers are companies - as business to business products and services are a huge part of the economy too.
