Not as a first step. I honestly think that we should first and foremost eliminate all the subsidies to overseas investment and to the hiring of guest workers in the USA. IMHO that may well be enough to make teh turn arround. However, I think tarriffs may prove useful for dealing particularly with those nations that engage in unfair trade practices such as the PRC and India with its capital controls. If, however the USA is still seeing a net outflow of capital then I would agree that a protective tarriff is needed. I would not have any problem whatsoever if the income tax was replaced with revue tarriffs as a means of funding the federal government. Nor would I have any problem with a national sales tax replacing the income tax.
Enterproise zones where corporate income taxes were eliminated and much eased regulatrions were in place would also make sense to me if the companies locating there in agreed to the maximum American content possible for all production therein in return for the eased restrictions. If such areas became the fuel for an economic success then maybe it would lead to these reforms becoming nationwide.
For certain national security industries I wqould prohibit foreign outsourcing for national security reasons. for example missle guidance systems.
