Most people are totally reliant on Social Security for their retirement, as few companies offer pensions.
Which means the majority of the people are totally screwed. Social Security was only meant to provide a portion of the retirement income. Basically for the majority of the population there will be no retirement, most people will be forced to work until they drop or can no longer find employment and fall into poverty. It's going to be the 1920's all over again in coming decades for the elderly.
