Can social welfare be measured by "adding up" peoples’ utilities? Why or why not? If not by using utility, how can policy makers estimate the welfare of government policies?

Social welfare can be measured by adding up the utilities of people when the benefits are distributed in such a way that no person derives utility at the cost of another person.

It should be noted that social welfare systems give assistance to people through programs such as health care, unemployment compensation, food stamps, child care assistance, etc.

The government can estimate the welfare of government policy through interpersonal comparison of utility.

Social well-being can be measured by the "sum" of public services provided to people.

Explanation:

A government, as well as policy makers, that promote efficient public policies aiming at the positive social and economic promotion of its population is promoting social welfare and the degree of that social welfare can be measured by the "sum" of the public services provided.

This is because public services, when performed in efficient ways, allow for the reduction of the needs of a society. A community that has all its needs met is a society with a high degree of social well-being, which can achieve very beneficial and uplifting standards of living.
