I'll start "on the other side"
Binary choices are not the best way to make decisions. As practice shows - it is more correct to choose a priority, but not an unambiguous choice. And so it is here in your topic.
Depending on the situation, age, future plans...
For example, if you are at the age before retirement, you will probably be interested in high income, so that pension accruals will be extremely high.
For a young person probably the choice will be in favor of knowledge - because it is the basis of his FUTURE.
On the other hand, I adhere to this concept, you should always learn and expand your knowledge. That means - always learn, always look for income channels (and always more than 1), always look for new knowledge and new income channels.
So the final answer is: you should choose both knowledge and income, and preferably a lot of knowledge and many channels of regular income
Smile, everyone needs money to survive especially on this new errand we are in now and also we need to educate ourselves too for the future so that we can embrace the changes Ahead of us especially now that the technology is growing higher and Advance that we need that education to be able to be part of it, So we won't be left behind. but we should remember education is the best key for successful life, without education or knowledge we won't be able to tackle the little challenges that may come our way during either on the job we are into or any other means. So for me what I believe in is this education, but the problem we are in now is that the world have changed whereby your Certificate of education cannot find you a suitable Job despite you are qualified for it , unless you are a politically exposed person or in close relation with an higher authorities then you are good to go, that's why many people try to grab the opportunity of jobs that will come to their way even without being an educated person, just to put food on their table for the consumption for them and their families. Therefore they both work hands to hands base on the economical situation of the country.
