Public investment significantly affects political relations by influencing economic growth and social welfare. Investments in infrastructure, education, and healthcare can bolster public support for governments and facilitate political stability. When investments yield positive results, they can enhance a government's legitimacy and encourage voter loyalty. Conversely, misallocation of resources or perceived corruption can lead to public discontent and erosion of trust in political institutions. Furthermore, the distribution of public funds often reflects and amplifies existing power dynamics, impacting the relationships between different political entities.
