I don't think trading is a job. Because for me real job is where you can make money daily from your hard work and effort. But trading is different, there's no guarantee that you can always make money, and you must always used capital for every trade and aside from that there's a risk of losing it. So for me, it's better to say trading is a business because it always has a risk same with trading. Despite of that, if the trader is not profitable and keep losing funds because they trade out of nowhere from the chart then it's called gambling, not a business.
I respect your opinion but I don't understand why you mean only manual labor by work. See workers earn money through their physical labor it is work just like a businessman earns money by performing business activities and sometimes incurs loss this is also work and those who do official work at institutional level also include work. But in any case everyone in the world earns their livelihood through work from their respective positions so no one is unemployed.
In fact, whatever the form of work, if the activity has the potential to make money then yes it can be called a job, or that means it is included in the class of work because it does produce money, but there are some activities that produce money that should not be used as the main income to support all life's needs. and an example is trading, because after all trading is always an activity that has risks, sometimes the level of risk can be very significant if a trader makes a mistake consciously or unconsciously.
So it's not a problem to get involved in the world of trading, but don't make it the main place to cover all your needs because the necessities of life will not be tolerated, in the sense that when you need money you have to have money at that moment, while trading is an activity. It's risky, which means that not every session you make a profit, that's why most people always choose a job that is certain with an agreement to get a monthly or weekly salary.
I don't know if your words agree with anyone else but it seems true in my present life. Because I did not make trading the only source of income in my life. But I think it hurts me to call those who do trading unemployed. Because everyone works hard to earn a living they should be treated with respect. And that is why I find it difficult to address any people in the world who are at least trying to work.
