We adjusted to it and I don't know anybody who makes a coherent case for it not making everyone better off, so long as we can figure out the accounting for the temporary, "pig in the python" problem looming.
There are lots of coherent cases against Social Security. For instance, there are far better ways to achieve the desired ends of providing a social safety net. My favorite would be eliminating all other forms of welfare and adopting a basic income.

Social Security is not even in theory aimed at providing a general social safety net, so its not surprising that there are better means if that is your goal.
