To be fair, it's not you lacking knowledge, it's a fundamental problem in the field of economics, which because of political reasons, has been dominated for the past decades by neoliberalism. The problem is that neoliberalism reaches conclusions that have been falsified by experimental data in several occasions, but since it serves the ideology of the elites, it's peddled constantly in media by prominent "economist" propagandists. If you're interested into the topic and this modern, more empirical vision of the economy, the field is called "Modern Monetary Theory" or MMT. There's a documentary released recently about the basics of it, applied to the US, called "Finding The Money", and I can also recommend the YouTube channel called "Unlearning Economics", which isn't MMT per se but it's very keen on treating economics through empyrism.
