Answer:
The correct option is;
Politics
Step-by-step explanation:
The average worker has the capacity to adjust the other factors of education, location, and productivity very well in order to improve their wages, but with regards to politics, politics is mostly influenced by the politicians and the industries are influenced by the entrepreneurs. As such the topics operate in different realms, with the politician pushing for the best interest of the average workers while the entrepreneurs can only help while still observing government requirements.
Due to the disconnect between politics and their wages is difficult for the average worker to muster enough politics that will lead to sure wage increase.
