The poor you mean, are the poor people who have jobs, or the poor who don't have jobs, because in my opinion there are also different levels of poor people. So if you mean the poor person who doesn't have a job. If you look at it as a whole in life, more or less it is certain, it will have an impact on the economy. Because even poor people who don't have a job must have needs and needs in their life, such as food and clothing that must be owned. And it's all definitely a must buy.
That way, it means that even the poor who don't have a job still have a contribution to economic turnover, although not too big.

And what about the poor, but who have jobs. The poor also certainly have an impact or contribution to the world's economic cycle. Moreover, these poor people have a job, but maybe with a salary that is not big.

So it can be concluded that poor people also have an impact on the economy, because if there are no poor people, it is sometimes difficult for rich people to find workers. And the poor are also basically the same, have needs and requirements that must be met. But the difference is only in terms of the amount of money and how often the need or needs are met.
