Final answer:
Option (4), Guaranteed income aims to reduce poverty, provide financial stability, and help afford basic needs. Through social services and UBI, it can prevent the vulnerability of specific population groups and promote a fair and equitable economy where citizens can thrive.
Step-by-step explanation:
The purpose of guaranteed income, which includes measures such as a universal basic income (UBI), is multifaceted but can be primarily identified as a way to reduce poverty and to provide financial stability for all citizens. Guaranteed income ensures that individuals have access to a minimum amount of money, irrespective of their employment status, thus helping to meet basic needs and afford essential services. Investments in social services like unemployment insurance, welfare, food assistance, job training and retraining, and Social Security are some of the means through which countries strive to prevent poverty, especially for vulnerable groups like the elderly and young people who grow up in poverty.
By setting a UBI above the poverty line, poverty could be instantly alleviated, but the policy could also impact the economy in various ways, including labor supply. Governments tend to aim for not only a reduction in poverty but also the promotion of a fair and equitable economy where all can thrive, thereby securing the blessings of liberty for their citizens. It's not just about survival but creating an environment where people can indeed thrive and find gainful employment that supports overall societal well-being.
