Two excellent posts by potatowings and readyfordeparture. They sum up the situation perfectly and I recommend you have a good think about what they say!
Unless you're a multi millionaire it's a massive gamble. If
the gamble pays off then you will be vindicated in your decision. But remember, this is a very difficult industry and unless you end up in a legacy carrier, there will no doubt come a time in your career when you may need to turn your life upside and go to where the work is! It's all about personal circumstances!
Good luck.
