Those who bought stocks a few decades ago or those who bought Bitcoin or some altcoins years ago, they would become wealthy by investment but today is not the time to become wealthy by investment. Today things are much different. To my mind, in order to become wealthy today, you have to be able to gain attention. For example, look at Instagram influencers, especially in fitness and beauty, they earn tons of money. They easily become famous, then companies pay them thousands of dollars just to post something about a partner company, then they also find investors and create their own GYM or supplement brand or drink brand and with their followers, they are able to massively promote and sell the product through their own Instagram and TikTok channels. That's how money is made today.
I agree with you that things have become different as there are more ways to make money and get rich these days than just focusing on business and investing like before. But it would be wrong to say that investing can no longer bring us wealth. The world is constantly developing, many professions and fields are born, in which technology is the top priority field . That means there will be more startups, projects, ideas similar to Apple, Tesla being created...or the crypto market is gradually maturing and will create more breakthroughs . From there, it will certainly create a lot of potential investment opportunities.
Investing is still an option , a good way to get rich these days.
