In the US. Problem is the US is infecting the rest of the world too, especially through subsidiaries which basically just translate from English the 'standard' employment contract.
I had to refuse employment in Romania since the clauses were so broad and basically illegal under Romanian law. (Of course, I had no interest in proving in court they were illegal but the contract was reviewed by an attorney on my side).
So, yeah, maybe apply some logic. If the employer owns your brain 24h/day maybe the hourly rate your are getting is not such a great deal.
And don't get me stared on clauses the survive the contract, including multi-year employment bans to competitors, etc. For a large multinational that basically mean you have to get a job landscaping or something because they compete with anybody would offer you a comparable job for your skills.
This 'standard industry practice' should die.
