This is the last thing im gona post about this to make my statement clearer, for those who read it later (dont wana go too off topic eh?).
There are indeed many businesses who make use of unskilled workers, such as in the agricultural sector where in some cases wage laborers are still used (people who get hired for the job at the beginning of the day and get paid at the end).
However in order to "generate more income so that they can pay for education etc", they need to have enough capital to do this, meaning that their labor has to be worth enough on the market so that their production is greater than their costs.
Unfortunately because they lack the means of production, they are thus vulnerable to exploitation by capitalists who themselves do possess these means, and find it in their interest to only pay the laborers enough to make them want to come back the next day. Many of the unskilled laborers can work all day but not make enough to accumulate capital after spending on their costs.
Not only this but these workers are in competition with one another. More workers without the means of production are constantly entering into the field (whether through immigration or because they are the children of the workers themselves), whether or not the price cost ratio is below the average, further devaluing their labor. Because of this those who are stuck at the very bottom have no chance of rising at all, their children might have a slim chance but because of the lack of capital they will find it extremely difficult to educate themselves, specialize, accumulate, and innovate in order to further themselves.
First off, you don't understand the real reason people hate going off topic. This is a legitimate discussion so it isn't frowned upon as pointless once sentence banter is.
Anyway....
The main point I'm making is still people can always make money, even if they will be losing most of it through living expenses.
Although a person's normal expenses may only cover their cost of living and nothing more, there are ways to make money in what would normally be leisure time that can be saved and put towards investments.
I personally worked an $8/h job during high school which paid most of my basic expenses like gas, auto insurance, food, leisure money. Granted, my parents feed me at home if I'm not out and put a roof over my head, this still covered all of my expenses and I only received as a check around $120 a week. This was a part time job where I worked only 15 or so hours. However, I did go to school for most of the day and was involved in various extracurriculars that took up time. Regardless, I was still able to pay my expenses. I believe that if I really had to pay for my own living, I could live in a very cheap apartment with a roommate and afford to live.
In addition, I spent my leisure time teaching myself web design and SEO. I started my own business with the money I made selling NP for other and doing various other online tasks on web design forums. I started a steady passive income by working in the little free time that I did have.
These people are not working 24/7. They are certainly relaxing and doing something to let off steam. This is, no doubt, necessary, but not all the time. They can make more money by either finding a second job or learning something online that they could sell as a freelancer.
And certainly you must know of government aid for students? If students are intelligent and did well enough in grades 1-12 to get into college, there are extraordinary packages for students who are disadvantaged.
I know someone who comes from a middle class family, but has a single parents. They are by no means poor. However, he is still going to school almost for free. FAFSA does wonders for helping students afford education. There are tons of government, private, and school grants available.
I love my food; yes I'm a glutton, but at least I know what good food is. Working aroung bologna and mock chicken all day (mock chicken is mechanically removed beef/pork/turkey and/or mutton formed into a loaf and covered in cheese crumbs... and for some reason it's really goupy and orange), I judge most of the customers and think "no wonder you're fat..." 'cause that shit is terrible for them.
