Why more population growth and high immigration won solve the dilemma?
More population growth, especially through high immigration, would be an illusory approach that will only pass the problem along to future generations. More workers today will inevitably result in more retirees tomorrow, thus requiring the addition of ever more new workers to support them. Realistically, increasing the ratio of workers to retirees could only be done through massive increases in our already historically high immigration levels. This perpetual growth treadmill would create many more additional costs that would far out weigh any benefits to Social Security.
