Hired a Certified IT or self Trained IT!!!

Many IT people learn technology thru self study, some are even very good on thier field but they have no certification bco’z of some reason. one maybe is taking exams to have certification is expensive enough for other IT people even they know some company looks for the certification when you apply for a job.Im not saying that IT pros. who have certificate are better than those who do not have.Why not some company give a chance to those IT pros. that have no certificate. or maybe taking the exam should be free of charge. I want to have a lot of certificate as IT pro. but i can not afford to take the exams.

If yes why?
If no why?
