There is a growing movement to eliminate 401(k) retirement plans due to questions about their value, with scholars on both sides of the political spectrum raising concerns. The tax advantages of 401(k)s, which cost the government billions annually, are being scrutinized, as they may not significantly increase retirement savings and primarily benefit the wealthy. As the government seeks new revenue sources, the future of these tax breaks is uncertain. Also, 401(k) alternatives could lead to reduced retirement savings if people find it easier to access their funds earlier.
