Nor is there any "evidence" of those economic failures merely opinion based upon ideology

There is "not any evidence" that interventionalism is a failed economic strategy?

No because of the inability to run economic experiments. Thus conclusions drawn after the fact are not very dependable.

If one could start from the beginning and implement a different policy one may be able to drawn sound conclusions but as the case maybe they are only opinion buttressed by theory.

There's plenty of evidence. Fakeit simply does not desire to acknowledge it because he knows he's got nothing to counter it with.

Exhaustive studies have been conducted on the three primary beneficiaries of protection in the early 19th century: bar iron, cotton textiles, and woolens. In all three cases it has been concluded that protectionism flat out failed to achieve what was claimed as its goal, viz. the stimulation of American industrial development in those sectors. Textiles and woolens both received no discernable stimulation and iron actually saw its production made comparably less efficient as protection delayed the implementation of the previous half century of technological advances in the smelting process.
