If you ask "should I get a PhD?" the answer is no. The only people who should get PhDs are those who want one so badly they are willing to put up with all the nonsense to get one. You are going to spend 5-10 years of your life working very hard for no money at all. If your advisor is an a**hat you might not even graduate or be miserable for the entire time you are there. In my PhD program of the four students from English speaking countries, I was the only one to finish. It was pure hell and didn't really help much except for the fact that people say "wow you have an ivy PhD? Cool." I would not do it again and would not recommend it to anyone unless you wanted to go into academia.
Get a job. Make some money. Be happy.
