Please be able to understand the difference between self-improvement and greed, because it is very clearly different. In today's modern economic era, we are required to always be able to develop ourselves and that is not something wrong. Getting a bigger income from the results of self-development is a fair result.
The times are changing, and so is the economy, in contrast to the conditions and conditions at the time a few years ago, when the price and quantity of goods/services were still very vulnerable, easy to obtain, even accessible, but now it's reversed, as time and time goes by. the economy is increasing, of course it requires us to be able to carry out our own research to change the good reality, the world and the economy is increasingly developing/advanced demanding a person for an adequate income even greater to be able to maintain self-development and life.
