It was possible to get a job in IT without a degree in the past but nowadays the only job you can get in IT without a degree is a helpdesk or end user support. Needless to say, you will end up with peanuts for a salary.IMHO a degree only gives you a better chance of getting an entry level job over someoine who doesn't have a degree. After that it's up to you what you make of things. I currently contract at a company whose CIO / COO (IT) doesn't have a degree and have worked at one of the big 4 auditing firms where IT audit partner never had a degree.
Experience and being able to do the job are the biggest criteria in the industry.
