What aspect of social security is often cited in discussions about residency requirements for benefits?

The aspect of social security that is often cited in discussions about residency requirements for benefits is potential financial instability. This is because residency requirements are put in place to manage the distribution of social welfare funds, and ensuring that only eligible residents receive benefits helps maintain the stability of financial resources designated for social security programs. If non-residents or individuals who do not meet certain residency criteria were able to access these benefits, it could lead to an increased financial burden on the system. This potential instability is a primary concern for legislators and policymakers who aim to regulate the program effectively, ensuring it can continue to support those who truly need it while safeguarding against misuse or overextension of funds.
