I'm not sure of the status of the PSLF program in the future but as of right now its been rough. Since the inception of the program, less than 1% of applicants who have applied for forgiveness have had their loans forgiven.
Now obviously 10 years from now there are a lot of things can change but I'm personally against relying on this program. I personally think people can guarantee their freedom from their debt by living frugally and attacking their student loans aggressively. Until this program greatly improves, I personally won't use this program.
