If you are going to make such a drastic change it will take a few more years to finish. We are starting an upward turn where hundreds of thousands of jobs were created just last month. Take into account that the baby boomers will be retiring over the next 5 years or so (most likely) and so jobs will start opening up in the coming years.

All I can say is don't choose a major based on pay - its better making less and really loving what you're doing. I get paid 15,000 a year - basically poverty level but I laugh basically the whole day and I LOVE what I do. Find something you're passionate in and it will work for you.
