For me according to my region, most people with the basic computer knowledge that are employed by companies earn something between $(150-300) per month depending on the company that they are work for. What is the situation in your country?
You are very correct everyday people are learning extensively so having a basic computer knowledge will never earn you much you can only teach on primary school where the wages seems low except you learn a skill like blogging or web development skills so that you will get hired easilyNowadays, having basic computer knowledge will not enable you to earn a lot of money because a lot of people have basic computer knowledge. To earn more, you need to have specialized skills such as how to make use of AI to increase productivity.
