Short answer - NO. Although I hold some certification I truly feel that this may not be enough to cut it. Over the past 20-some years I have seen many people come and go in this environment, some certified, and some not. To this day I still believe that you must do this type of work because i) you love doing it, and ii) it comes natural to you.
The people that 'get into' computers because their high school teacher tells them it is "the way of the future" should look elsewhere for a career. If this is all people base their choice on they will be very disappointed and frustrated when working with computers. The next step is of course grabbing as much certification as they can. Again, I've known people who got everything from A+ to Z+, and their logical train of though derailed at the station. They couldn't think through a problem systematically or logially, and they soon ended up finding a job in a factory or gas station. There is a difference between memorizing answers, and learning the material. Or, to quote a Jedi the difference between Knowledge and Wisdom.
In summary, if a person fits the profile to be in the computer field, if they can think out problems with some logic, then yes - get as much certification as you can.
