Firstly, Let,s talk about lower income, why we have a lot of people have lower income, the reason of that might be , they do not have job , or maybe have a job but they just have a few wages and so on , because of these reasons they become a lower income taker, and that means they can not afford their normal life, for example ,
now , the price of a lot of products are increase , and if you are a lower income taker you do not have enough money to buy them , like some daily goods, food , or something else , and you just can use the money that you can afford to buy something you can buy, and because of that , there are some drawbacks of that, for instance , when people can not afford their life, they might do some bad things for society, like steal,heist ,abduct and etc, and the government in older to make these solutions go down ,they will constitute subsidy for lower income taker, and make their life better than before and decrease the crime.
Secondly , we talk about the middle income taker, if you are a middle income taker that means you have job and you might have normal age ,,not very high,but it is enough for you . a middle income taker's life is better than lower income taker,because they have money and can afford the normal life, they can buy necessary goods that they need and a few luxury goods which they can afford, and also middle income taker near upper income taker , so some people who is middle income taker want to have more money to become a upper income taker , they will work hard ,and it is good for firm and productivity.
Finally, i am going to talk about upper income taker, a upper income taker,means you have a good job with high wages , and you can afford your life and more than that , for example you absolutely can buy all of the things that you want ,maybe luxury goods , and you can have a rich life and etc.But because you know you have enough money maybe more, you might not very hard to work , the productivity will decrease ,and your wage might be go down because of your attitude by work.
