The tariff of 1816 benefitted the northeast and the south equally

No, it did not. The tariff of 1816 only made the south angrier because not only did they have to pay the importation taxes(for farming supplies), but they also had to pay the exportation tax to send it to the outside world

Hamlet's fourth soliloquy is probably his most famous one - "to be or not to be."it is rather different from his previous soliloquies because now he is contemplating something that didn't come up before - suicide. he is thinking whether it is worth it to fight to find his father's murderer when in the end all of them are going to die, so why not die sooner than later. he is contemplating if he should go on fighting or just kill himself and end it all, which is why this soliloquy in particular is rather depressing, hesitant, and gives a deeper insight into hamlet's madness.
