Fortunately for the Union and unfortunately for the Slaver Insurrectionists and their defense team, Hamilton's program laid the basis for the development of a strong capitalistic economy in the North which allowed the creation of and arming an army capable of defeating the insane designs of the Slavers.
This is the reason Hamilton is so despised by the DSs. Had his program been a failure and weakened the North you couldn't have been happier.
Of course, it is typical misleading nonsense from you to compare an infant industry with a small market to British operations able to produce for a world market such as the Empire. Economies of scale produce the profits capable of drawing forth investment from the largest banks in the world at that time, the British and even the larger European ones. Comparing apples and oranges is pointless.
More venom, yet still no content or substantiation. The simple fact of history is that the major industries that protectionism was supposed to help - textiles, woolens, and iron - did not experience the anticipated technological growth spurt and in fact lagged behind with inferior and antiquated technologies. That fact has been thoroughly documented by several very distinguished economists including Frank Taussig, nobel laureate Robert Fogel, and Paul David to name a few. Hamiltonian protectionism was a failure. Live with it.
