This is Kawaguchi Hidetoshi. This is my humble answer to the question.
Certainly, “income” is one of the things I'm worried about and compare...
“Comparing” was addressed in the recent question “3 months since my father passed away” (http://hasunoha.jp/questions/404).
Now, in the world, high or low income is one standard for high or low value, so that can't be helped.
Money is certainly important. But money isn't everything. Also, various examples in the world show that money and happiness are not proportional. Even so, there's no denying that there is better than nothing, and anyway, no matter what you do, if you don't have anything that naturally precedes you, the reality is that you can't do anything. I need money. However, it is necessary to understand well that money is only made up of the value of people's trust, and it is also necessary to understand that it is sometimes extremely dangerous and fragile. I want to continue using it meaningfully and effectively before the value drops.
Now, in terms of Buddhism, how should we think about income... Of course, money issues are the most likely subject of obsession or worry, so it is necessary to be especially careful. Rather, if there is one, it is recommended to accumulate good works by using it for good deeds through devotion. Also, if there is a good reward as a result of that good work, it would be even better if we decided to do even more good work.
As one of the episodes of Buddha's alms, it is said that when attending alms, they intentionally went around poor houses. If you think about it normally, you would think that going around rich people's houses is a matter of course, but it includes deep insight into the theory of causation and karma thought of in Buddhism, and it is said that this is because the poor had a feeling of mercy that they wanted to rescue them from that poverty by somehow accumulating a good cause called ki-dosing.
Anyway, rather than income, I would be happy if you thought a little bit about how well money can be used for good deeds.
