The outcome would have been the same if the author was an engineer as well. The point is that the immigration is tied to your employer and unnecessarily long/complicated and full of uncertainties (such as lottery).
For example, let us say you are from outside US and got an admission to Harvard for MBA. Now what you have to decide is whether it is fine for you to spend ~$200k in 2 yrs in education at Harvard and then potentially returning back to your country since if your name doesn't come in the H1 lottery - that is what you have to do. There is no 2nd chance. These kind of decisions is what is keeping out a number of bright ppl from coming to US and look elsewhere for opportunities.
