Economists widely believe that Pareto-optimal allocation of resources in relation to public goods is not compatible with the fundamental incentives belonging to individuals. Therefore, the free-rider problem, according to most scholars, is expected to be an ongoing public issue. For example, Albert O. Hirschman believed that the free-rider problem is a cyclical one for capitalist economies. Hirschman considers the free-rider problem to be related to the shifting interests of people. When stress levels rise on individuals in the workplace and many fear losing their employment, they devote less of their human capital to the public sphere. When public needs then increase, disenchanted consumers become more interested in collective action projects. This leads individuals to organize themselves in various groups and the results are attempts to solve public problems. In effect this reverses the momentum of free riding. Activities often seen as costs in models focused on self-interest are instead seen as benefits for the individuals who were previously dissatisfied consumers seeking their private interests.
