Idea that Bitcoin is only for rich is common misunderstanding which mostly people think and this is due misleading on media. And we know high transaction fees during busy times can make small payments expensive and keep in mind that Bitcoin is for everyone and we can buy satoshis if we can not but single Bitcoin .

Bitcoin is neutral which can benefit wealthy people and also to poor people depending on how they have plan to accumulate it especially in places with unstable economies where it can provide financial access and protect savings. Its real power comes from being decentralized and open.
