On a ballpark..If you are making at least 3 times of ur current salary..ie. around 3 lacs per month. You can explore to come here. However, always remember why you came here. Get your money and consider anything else that you can get as bonus. Just like everyone else, I am sure you will have your own unique life situation so act accordingly and I dont think earning money or desiring to earn money is greed...Greed is more akin to what you do with the money that you already have. Wish you all the best in whatever you decide.
