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.
Trading is also a real job that can be learned by everyone in order to get the opportunity to profit after trying it several times through certain exchanges. Because now opening a business and selling manually is very common for everyone to do, so those who don't have the space to do it manually can try it through crypto exchanges and other exchanges in order to still have work activities and make money when they have a profit. And from the example you gave, it can actually also be good advice for those who keep complaining on the grounds that they don't have a job, even though they are the only ones who don't have the will to work.
