Why did so many battles on the western front lead to stalemate?

Stalemate developed along the Western Front because they tactics of offensive warfare had not developed while the technology of defensive ware fare had.

During WWII, rationing was allowing the American family/person a certain amount of food, sugar, clothes, and weapons. Things that would've been easy to get and in surplus during peaceful times could only be bought in small amounts. 

War bonds were basically bonds that removed money from circulation to fund the military or government. Anyone who invested in one would help support the military and help lower the prices of goods (since there was less money in circulation, things were priced lower). 

Internment camps particularly affected the Japanese and Japanese-Americans. Put simply, during WWII, America was fighting Japan, and was very suspicious of the Japanese in the country, believing they were Japanese spies. The US government put the incoming Japanese in "internment camps" which more like prisons. It was estimated that around 110,000 and 120,000 Japanese living in internment camps along the west coast.
