This is a common misperception but it’s not that simple. Here’s an old study discussing how it varies based on the field, where the lower level jobs do tend to pay better but higher-skill jobs have the opposite trend:

Since the Obama era, this has gotten worse because there were a ton of people trying to score political points saying they were cutting waste by freezing civil servants’ salaries and that really got ugly in tech jobs because salaries were booming once things like the Silicon Valley wage collusion lawsuit and high demand for security, DevOps, etc. started raising the ceiling for the private sector. In 2010 the top end of the GS scale was competitive once you factored in benefits, hours, etc. but a decade later that just wasn’t the case. I knew multiple people who were trying to stay in the public sector but it was literally 2-3 times more money if they went private even though their skills were considered mission critical for their agencies.

This sabotages contract work, too, because there isn’t anyone qualified to guide or review the work and that tends to burn orders of magnitude more money than simply paying more directly would.

That study is a decade old and covers a very limited 4 year period right after the big 2008 recession where the private sector took big losses and had a glut of college graduates competing for entry level jobs. Even then it shows specialized and highly educated workers doing far better in the private sector.
