It also makes it hurt more when you are laid off and the illusion is broken.
You only ever work for yourself. A single employer means you have a single client. It also means you only have one source of income. That is always risky, because work done for others is always temporary. Honestly full time employment is way way -more- risky than being an independent contractor with a few small predictable retainer contracts.
Also key to remember is that no matter how rewarding and interesting the work is you will eventually lose access to that too unless you fought hard enough for it to be open source.
If you want a job where losing that job is tantamount to company failure, start your own business. When it fails (and statistically it probably will), your failure will also lead to your job loss. Congratulations.
If you "have a job", you're accepting being a cog in a machine that's primarily not about you. I make that trade-off, as do most people, but don't mislead yourself about what's going on.
