I've never agreed to these since graduating university. One time someone tried to get me to sign that anything I invented for the next 3 years that was related would be their property. I've found three good pushback techniques: 1. "My [insert family member] is a lawyer and I haven't seen this clause before, so I'm going to get her to read over the agreement." Next day I just say that they won't let me sign it. Why make up a family member as a lawyer? Because to push back or hire a lawyer is viewed as an aggressive move, while affably showing deference to your family member isn't. Later in life when the job / contract offers started getting bigger: 2. "I don't sign things I don't intend to follow and I'm going to be building things in this industry on my own time for my own profit." Strait up confidence along with the fuck-you attitude to back it up by walking away. I'm never going to work for someone that is that dense and short sighted anyway. Every single company has allowed me to just strike out the clause and have us both initial it.
