I think most of the wealthy people have huge sums of money are more interested in trading instead of investment and those who have a limited amount of money are interested in investment as they think that if they keep their money in beneficial assets then after some years they will be able to make their economy better.
Not all of them are like that, mate, because there are also rich people who invest and trade at the same time, even though the investment they make is for the long term and the trading they do is for the short term. I also don't blame you for what you said because there are people like that in this world, but this doesn't happen to everyone so we shouldn't judge everyone equally. Because people who don't have a lot of money also dare to trade as long as they have the knowledge and mental strength to do it.
Those who leave their job for investment or trading are the foolish person and they will realise about their mistakes if they continuously lose money through trading and will then be feeling sorrow to leave their job.
Don't immediately call other people stupid because they left their jobs, maybe they themselves think it's time to stop being slaves to other people with a small salary so that those who make such decisions are also based on more mature considerations. Even though they will also understand that in terms of trading they will not always be profitable, but as long as they have the courage and mental strength to continue doing this, I think they will also get profits that can even cover the losses they have experienced before.
