as mentioned above the people most like to make negative remarks about FAA licences most likely possess two basic qualifications..
1) Lack of understanding of the total FAA system
2) The desire to work in the USA under the privileges of an(inferior) FAA ATP should the INS allow it...keep in mind....
most US major airlines successfully complete more SECTORS in one year accident-free(with inferior licenses/training) than overseas competitors complete in a decade, in a large variety of weather conditions, congested airports...etc...etc...so you figure it out...
