Pro-Trump video uses Kamala Harris' own speech against her

A pro-Trump video shared by Donald Trump Jr. uses a short video clip of Kamala Harris giving a speech. The speech was about high costs. Kamala pledges to fix high prices if she's elected president - but most people have the same question and want to know why she isn't fixing it now? Kamala Harris has been in office for nearly four years, so she's already been in charge and already had the chance to fix things. So why would people want her in office for another four years if she and Joe Biden didn't fix things already?
