What is one reason the government has limited control over spending?

One reason the government has limited control over spending is the influence of mandatory expenditures, such as entitlement programs like Social Security and Medicare, which consume a significant portion of the budget. Additionally, political dynamics and the need to accommodate various interest groups often lead to spending commitments that are difficult to reduce or eliminate. This can result in budgetary constraints that hinder the government’s ability to exercise full control over its expenditures.
