This is only true for US salaries (and sometimes specifically within Bay Area/Seattle/New York markets)... pretty much everywhere else, salaries are a lot lower.
L7 salaries are 300k base and around 400k equity in the US, so hiring experienced/accomplished developers is intensely difficult for companies outside of the top tier with high margins or startups with potential exits.
Definitely only true for US and certain geographical areas, including the one I'm in. All I'm really saying is top-tier, experienced talent in top paying geographies make significantly more than $200k.
