It isn't a viable career choice - now, more than ever. I recall being told in the mid seventies that writers were poor, and it's true. Earning money as a writer has always been difficult.
Now that 84% of Americans want to be writers, and with 600,000,000 blogs on the web, the problem isn't with the shortage of writers. It's with the shortage of readers.
Writing as a job is over-subscribed. And because many people are prepared to work gratis, there's no need to pay them much.

Just in the USA, there are 32 million bloggers. 7 million blogs are posted every day.
According to the IRS, the average income for writers is $1000 per year. However, if you want to combine writing with advertising, affiliate marketing, etc. you can earn good money - of course, you have to have the traffic, and that's the hard part.
