Although investing can help us deal with inflation or even make us rich, investing is risky so it is only for those who are ready to take risks, not for those who are not ready.
People who refuse to invest and give reasons like they don't have a stable income, low income, don't have much money...simply because they don't want to take risks in exchange for bigger rewards.
Besides, financial investment is not the only way to help us become rich. Investing in yourself through education, skills or investing in people such as business, startups...can also help us become rich. Don't limit our thinking and be too rigid that only financial investments can make us rich.
Yes, you don't need to be rich to invest. You can even invest with just a few dollars. But believe me, there's a big difference between investing a few dollars and hundreds or thousands of dollars. I'm not saying investing a few dollars is bad. But the reality is, investing should only be done by people whose income is sufficient for their daily needs. We can't force someone who barely even makes enough to live on to invest. Furthermore, we must have an emergency fund before trying to invest. I have a friend who regularly invests around $30-$50 per month in Bitcoin and stocks. But he can't hold it long-term due to unexpected expenses like hospital bills and car repairs. He has to sell his Bitcoin or stocks when he needs money. This means he doesn't have an emergency fund or non-investment savings.
