It would also be advised that you learn how to write above a fourth grade level. Perhaps all to tautly, the main point to this career option is that there is a demand for full-stack marketers. This would conclude that within the producer-employee market, there exists a deficient amount of marketers with these qualifications; for lack of a better term, an oligopoly-like employment situation (which can only be short term, what with structural unemployment). So if there would be a sudden shift to this career choice, and there will be if it is such a relatively easy and beneficial option, the employee market would lose it’s oligopoly control in contract work of this sort. Here, the salary would diminish quite quickly, due to the adjustment in economies to scale. This is, of course, considering that such a universal job can somehow work for everyone. I believe the main hypocrisy, as you ironically stated near the start, is that no advise holds objectively constant. Good effort though.
