I also wouldn't want to be an employee. I work best in short monthly bursts with legitimate breaks in between. I'm working on setting it up so I can do that as an experienced consultant/freelancer.

The job market is pretty different though for full time employees - one part of which is the insane contractor usage at big companies with money. Microsoft is still like 50% contractors, and in this area if you have "contractor for a bigco" attached to your resume I'd estimate you'll be talked to by far fewer recruiters, and then offered less lucrative work. Also as others have stated you'll have up to 60% of what the company pays for your work taken by the contracting agency especially if they do "management" for their workforce.

Then benefits are a real thing. I have some healthcare needs which require me to have consistent insurance that isn't going to force me to other providers just because I switch. Retirement investing without a 401k is basically all cash since the roth and regular IRA limit is so low. I'm still figuring out how that will work, whether I should incorporate as a consultant so I can provide a 401k to myself, or just not bother with it and just invest.
