In addition, those who have some sources of income will not direct everyone in a row, thereby creating competitors for themselves.
You know, I've often tried to find out why a great deal of people hoard knowledge but I haven't been able to place my finger on it to be holistically on the basis of rivalry. I ain't saying we can completely rule out rivalry or the need to protect one's businesses but that isn't all to it. Let's take trading for an instance. Why do people hoard that knowledge which gives them near perfect entries? A trader's winnings won't stop another from winning, does it? Of course, not. Despite that, we still find traders who don't like to share their strategies. Take for instance, Trader A who lives in Canada could be trading on Kucoin while Trader B lives in Dubai and trades on Hotbit, there's little or no chance at all for rivalry. However, the human ego of being the best in any field of endeavour will still make any of the traders who is profitable still hoard information.
I didn't mean trading. There, as they say, everything depends on the experience of the traders. I doubt that you can learn to trade in such a way as to always remain in the black. I believe there is also a place for luck, but by using the phrase you highlighted, I meant the difficulty of finding a good job on the Internet in general.
Likewise, I had a job like this for a while. There was a closed group, which included only people we knew, and we did simple work on the network. We were paid for this, but the organizers were ready to accept even more people, which did not suit us completely. We just worked harder and as a result, the pay was decent, but if we expanded our company, then, you know, we would lose in earnings. It is very difficult to find something that requires almost no labor, but it pays. And it's on the Internet; you just need to know how to find it.
