Everyone can learn and try to trade, but is it for everyone especially for those who thinking that trading is a some sort of quick money making scheme then it's not for them. You won't get anything if you are new unless it's beginner luck. If you want to go into marathon way and want to learn and experience the worst trading feel with losses then it's for you with every losses make you stronger and want to learn more and more.
Otherwise, if you are a person that is easily demotivated once something bad happens then you better stay away.
Well,thats your opinion,but to me I just think it's not everybody that can trade,some persons don't know about it,while some persons who know about it are scared of it,they think the moment they get anything to do with it,it will just sweep away their money.While on the other, people who have known about it,who still suffer loses despite the different strategies they have tried to apply now feel reluctant on trying more because some thinks it's not their thing,while some thing trading is bad.That is why I can just conclude to say trading is not for anybody.
I said learn and try, it doesn't mean that all people will have the same result even though they learn from the same sources. For me personally, I do trade occasionally because you said that sometimes it's not worth it in these days to do trade especially with how busy you are in real life and I do respect that. Even when they think they "master" of this particular subject, it doesn't mean they will do well.
There is nothing bad in trying, what I can only term as bad is for one not to try at all but be complaining and give reasons. One may try and fail, it doesn't matter, however, if such a person can be persistent about the whole thing, I am sure that success could happen, it might only take time. Trading is very risky, but not only that, it is systematic in nature and needs patience, it takes regular practice to unlock that and once you know it, you can be profiting easily. But now that you complained about those who do not have much time for trading due to their busy daily schedule, well, in my view, it might be an issue for them when learning, but when they've learned well and are fully experienced, they might be trading the long-term disposition. I am sure that they will be needing only a few minutes of their day for it. Like myself, if I am handling long-term trading, I might not even spend up to 5 minutes making my analysis and monitoring my active positions.
