Some people do make that much money as employees in this industry, I doubt a lot do, but I did for 3 years.
To get that you have to have the right owner in a large market and be dedicated to your job. If you call in sic more than once every couple of years, frequently use all your vacation days or put your playtime first you will probably make 2/3 at best. If you care about the company as much as the owner, relieve a lot of stress, do things because they are right, not because your supposed to, and you have a wide range of skills. you can make that much.
You are going to add some stress to the owners life because you'll want to push the boundaries of what you and your company can do. The owner will learn to trust you and you will get compensated when you are consistently successful.
In my situation the fact that the owner never put me on salary helped because I made a lot of overtime. I also had several large jobs follow me from the previous company and I got commissions on those as well (we didn't pursue them. They called me as the other company stopped being responsive). At my new job I also got certified and started pulling large national account jobs and I got commissions on these too.
The first time I made over $70,000 I asked the owner how we did as a company, best ever, how he did personal, best ever, and my response was me too. Felt good and everyone was happy.
