So maybe MS isn't such a bad company the keep the IT sector booming with new security jobs
If Microsoft went out of business (something that will happen soon after the insurance companies get their act together) there would be just as many, if not more security jobs.
This is partially due to the growth rate of the security industry, and partially due to the fact that a poorly configured Linux/BSD/whatever system is at least as vulnerable as a well maintained Microsoft system. Individual system security is also only a small part of the industry.
