In fact, the situation does not become too problematic until 2034 based on current projections, which gives ample time to fix the system. Even if the system is not fixed by 2034, that does not mean that Social Security would disappear entirely in that year. At that time revenue would still cover approximately 79% of projected benefits.
In a worst case scenario, people would most likely just receive smaller benefit checks.
There is still plenty of time to fix Social Security despite the fact that the two major political parties disagree on how to fix the system.
