Which US amendment guarantees the right to due process, and which continet, excluding North America, has the most geographic coverage/ landmass with protections of due process?

the fifth amendment guarantees the right to due process and south America has most geographic coverage

i think it can have both positive and negative effects on businesses.

for example:

lets say you own a small business and taxes go up 4% that means it is going to cost your business more money to buy product to sell. but at the same time you make more money from the tax rise.

that is my theory.
