<prompt> Human: I would like to understand better a point about social security. I have a single salaried job and no other income, my employer withholds my taxes. I am 30 years old. A certain portion goes into social security. I have two questions:1 Is there a way for me to calculate exactly how much social security I can expect to draw when I reach the age requirements, assuming I quit my job tomorrow and only paid in what I have paid in up to now? I ask because this kind of calulation may influence my early retirement strategy.2 Is there any risk whatsoever that what I put into social security will be lost due to future legislation? I.e. I want to understand what sorts of guarantees I have or do not have about retirement. So basically, what I am asking is can I precisely understand what my social security income will look like several decades from now, or does everybody just wait and see and be happy with whatever comes their way?  <response>: So basically, what I am asking is can I precisely understand what my social security income will look like several decades from now,No.
