The only disadvantage of europe could be that the wages are lower but it is normal. In europe they don't give your salary and leave you alone. You don't need thousands to live better life because there is social state. Health is free, education is free, you get money for every child yoi have. A lot of social benefits that removes the need of US level salaries. Maybe people from outside just compare the numbers and say ok in the us they pay more let me go there, but the reality is different. IMHO in europe you have a safer future even you see less in your bank statement.
