Of course. Escaping one of the highest corporate tax rates in the world can have that effect. Not to mention escaping unions, regulatory handcuffs, and much more.
Unions are basically dead. Less than 10% of the manufacturing workforce is in a union. The sole driver of offshoring is to NOT pay first world wages for labor. Labor is only a small part of manufacturing costs, less than 8% in most cases. More like 5%. But 5% is a lot to add to a bottom line, regardless of the destruction it causes in the USA, socially, politically and economically for the individual and taxpayer with little or no benefit.
