Why is the public sector required to provide certain things at resonable coast?

The public sector is required to provide certain services at reasonable cost to ensure equitable access for all citizens, regardless of their economic status. This is crucial for fundamental needs such as healthcare, education, and public safety, which are essential for the well-being and development of society. By offering these services at affordable rates, the public sector promotes social welfare, reduces inequality, and fosters a stable and productive community. Ultimately, it aims to uphold the principle of the common good, ensuring that essential services are not solely dictated by market forces.
