Lol these threads are funny because they always focus on the bottom feeders or the absolute worst of one group and scale it up as if it's the majority.
If I was to play along with this train of thought, the number one answer would be trust or fear. Why should I trust you with my hard earned money? Why should I trust you know what you're talking about? Is there some kind of insurance on my investment? What if I lose everything, all because I decided to listen to some slick nigga in a suit, will I be able to live with myself?
These are the questions that are running through the minds of most potential investors.
The next answer would be, presentation. Most of the people I've witnessed and spoke with regarding financial literacy are absolutely terrible at stating their case. They sound like con men, they're condescending, they're nerdy ass, thesaurus using ass niggas, or they don't know how to get their point across. You have to present it in a way that your customer can comprehend what's going on. Explain the concept of investing in general and connect it to something that's important to them or something they're already doing. A lot of the bottom feeder ass niggas already practice some form of financial literacy, when they save up for concert tickets, festivals, vacations etc.
...To the thread starter, if you want to truly help people, get with someone or a team who can truly articulate your ideas and is a chameleon of sorts when it comes to presentations. They know what language to use depending on the audience. Your position is better served as the bank. You're too far removed and negative to effectively touch the people directly.
