I looked at the date of this post, and it said "today", so I'm going to assume that means 5 September 2020. We're 6 months into the U.S. response to the SARS-nCov-2 pandemic, otherwise known as the Coronavirus, and the economy has, in a word, tanked. Many, many people are desperate for ANY job.
Unfortunately, employers don't want to hear that, because they just don't care. Yes, it's logical that someone would be unemployed because their firm let them go due to COVID-19. If they're not getting callbacks on their resume for jobs where it would NOT be a step down, after a while, a job seeker will start getting anxious.
As others have said, focus on why you want the job, and what benefits it will bring you, but focus on the benefits on a professional level, not the money. It's kind of why I, as a taekwondo black belt, still practice the fundamentals and the basic introductory forms... you're solidifying your foundation for the future.
It sucks that you can't just say "I'm unemployed, I want to work, I need the money to live", since it is the truth, but employers don't want to hear that, because even if it isn't true, they'll be afraid you'll jump ship at the first opportunity. In this economy, that's not likely, but that's what they'll think.
Spend some time doing research on the company, and on the type of position you're going for, and see how it will help you in your long term career path. Deflect any questions in that direction, and you should be fine. It worked for me when I was last unemployed, and that was 2013/2014.
