I don’t need to present a perfect alternative for my critique of Western Democracy to be valid. Critique is the means by which we can improve upon what already exists. Some short-term solutions could be to overturn citizens united and end legalized corporate lobbying, introduce voting reforms such as abolishing the electoral college and switching from first past the post to ranked choice or star voting, or expanding direct democratic programs like ballot initiatives. All of these have the effect of minimizing the influence of capital and maximizing the influence of people on the political process.
Longer term solutions involve bottom-up organization of things like mutual aid, unions of various types, decentralized infrastructure, community-run libraries (and not just for books), community gardens, etc. These kinds of dual-power structures always start small but have outsized positive effects on the communities they form in. If they were allowed to grow unhindered they would eventually grow together and easily supercede the top-down power structures that pervade our lives today, which is why they end up being suppressed or co-opted by the same.
A good example of how this occurs is how despite the internet providing a way to collect and distribute all the knowledge on earth for free to everyone on earth (the greatest library in all of human history), powerful corporations - with the help of governments around the world - unnecessarily spend vast amounts of wealth and resources to restrict the free exchange of ideas along socioeconomic lines.
