Your last sentence you’re saying it’s fair to make this assumption that most other jobs are worse.
So that means if a non-startup offered you a better pay package your assumption and bias might steer you away and take worse compensation to do the same job.
I ask you this question because I made a similar mistake in my youth. I took a pay and benefits cut for a startup because it sounded a lot more fun. 6 months later and the company was going under and I was out of a job.
There are also plenty of employees who just didn’t get a job offer elsewhere. When I took my first startup job I didn’t have a competing offer.
