How to pay for college with no financial aid OR help from parents?

Parent loans because they do not really have the money could be trouble in the future. It more likely that they will depend on your future earnings for retirement, since they will be paying down those loans instead of saving for retirement. This can have the effect of forcing you to chase money when making life decisions, such as taking the highest paying job now rather than choosing one that may pay less now but you like better and has more favorable future career development prospects.
