Because of this I am less attached to the work, there is more wiggle room, and I am less stressed about meeting deadlines.
Expectations from management will also be lower because you are a new-hire without any context. I'm not even going to get into the huge salary bumps you'll receive by hopping instead of waiting and fighting through performance reviews for a raise...
Most good raises come from quitting and changing jobs. The first few months, once you've passed the interview and been accepted, you have ridiculous room to be a loser (not suggesting you are) before the company will begin to recognize that.
Consequently, you may look around and see a lot of actual losers who are underperforming because they're lazy or inadequate.
Freelance, learning to play the consulting game, charging a lot, and negotiating unreasonable things (like pay me in advance for a year of income and you have my attention for a year for any project) is the way to go for people who feel this way. Or you build a SaaS or other business and make it work. Or marry rich.
