Final answer:
The Act's lack of lasting impact stems from collective action problems, individual self-interest, legal loopholes, special interest group influence, and the federal system's checks and balances which create barriers to enduring reform.
Step-by-step explanation:
The Act has been prevented from having enduring results for several reasons, including collective action problems, opposing financial interests, and the dynamic nature of politics. Individual desires and short-term thinking often subvert sustainable practices, posing a significant challenge to long-term success.
Furthermore, legal challenges and the ability of interest groups to circumvent regulations impede the effectiveness of reform efforts. Legal loopholes allow big business and special interest groups to continue influencing the lawmaking process. The federal design, with its system of checks and balances, sometimes blocks responses to national issues, as seen with clashes over laws like the Affordable Care Act and the Voting Rights Act of 1965.
Lastly, historical resistance from financially motivated counter-reformers, such as landlords and business interests, can slow down or undermine reform processes, despite public support and necessity.
