#1: Freedom to choose any career. Some choices are easier than others, some require hefty student loans or years to fulfill, but they are choices.
#2: Freedom to open up your own business: no bribes, long waits, or excessive paperwork required. And no, a 5 page master business license does not count as "excessive." Talk to Europeans about what "excessive" means.
#3: Free public education. It may not be perfect, and depending on where you live, it may not be great, but everyone can go to secondary school and graduate.
#4: Freedom to choose types of training, colleges, and college majors, without a single uber-test determining your lifetime eligibility for a career. SAT and GRE don't count. Many countries have strict entrance requirements with one time exams, when you are 16 or 17 years old, determining your working future - no "do overs."
So celebrate choosing a career in America. We may not always be happy with the financial or time requirements of our career choices and are sometimes overwhelmed by the number of them, but at least we have them.
