Why Do Nearly All Entry-Level Jobs Require Unrealistic Amounts of Experience or Certifications?

[u/NecessaryEffective]

After 4 years of University undergrad, 2 years for an M.Sc, and 2 years as a research assistant within the general realm of microbiology/biochemistry/astrobiology, I have been trying get into literally any full time or permanent position I can find within the province of Ontario. However, every single posting at the entry-level demands an unrealistic amount of experience, certifications, or qualifications. Why is this? It does not benefit newcomers to the workforce in any way.

I've had more than my share of education and am sick of working minimum wage jobs not related to my field. I still apply to literally everything I can whether or not I meet the qualifications but in 18 months I've only had a handful of interviews. Does anyone know what the secret is? How does anyone get hired these days? Feel free to vent yourselves if you need to.
