That is your claim not theirs. Trying to claim that his policies were a failure is not a viable theory though at times the general theory that tariffs don't work as planned surfaces from time to time. Neither side can be proved empirically and theoretic claims are just that.
This is unarguable though- Hamiltonism was designed to transform the new nation into a capitalist economy and spur the growth of domestic industry; the new nation's industrial sectors began to grow rapidly after it was passed and continued to do so until the 1830s when Jackson spiked it by destroying one of H's major institutions a major factor in that growth. Those sectors he had stimulated resumed their growth after the Jackson Depression was worked through. Is this a Liberty Valence situation were something else caused this growth? Not that I can see. And the fact remains that by the end of the 1800s America was the greatest capitalist power in the world with an industrial capacity second to none.
Whoop! There it is!
The purest, drossiest, scum-fluffiest Hamiltonian power-junkie madness, and ends justifying means to the nth degree.
How very David Rockefeller of you, O Master of the Universe!
Just goes to show you, GOP, just how pallid and unwinsome that old, honest republicanism starts to look, when you're mainlining raw power.
It's a matter of simple fact, fakeit. Either the policies succeeded or they did not. The explicitly claimed purpose of the policies - to foster the "infant" development of specified recipient industries beyond what would occur naturally in the market - is also necessarily the benchmark against which their success may be determined. Thus, to show them a failure requires only to show that the given industry's growth was either on par with non-intervention or inferior, as in the policy actually retarded growth. Taussig did just that with qualitative studies of iron, woolens, and textiles - the three main protected industries. David did an econometric study of textiles and found no gain from protection. Fogel did an econometric study of iron and found that protection slowed the replacement of inferior smelting techniques. That means protection did not boost those industries like it promised. That means the policy failed and your bizarre Hamilton fetish will never alter that fact of history.
