You're not by any chance a university student are you? Conspiracy theories, can't be wrong and no legitimate explanations for why you're 'right'.
What you're talking about is economic theory -
https://www.economicshelp.org/blog/1...ply-inflation/ - which is based on a lot of suppositions and with a key phrase - "though not always". It's entirely based on the premise that if there's more money, people will spend it and guess what, that's not always the case.
fyi, another post shared a link to the Bank of England website which gave the definition of inflation - not what you're talking about.
