What are some of the factors that affect government spending decisions and why do they have such an effect?
State debt is one. The more debt the state has, the less money it has to spend. Another is which politicians are in charge. Different leaders and different political parties often have different priorities and disagree about what to spend money on. Finally, constituencies are important. Politicians want to remain in office. Therefore, they have to consider who elected them and what their constituency wants when deciding how to spend money.
