> shouldn’t we prioritize on skill instead of using a lottery

Why? It's not a prioritization based on employer needs or what employers want. Obviously if one has a degree they enjoy being a protected class, and if they don't have a degree they don't like being discriminated against. At least a lottery gave equal opportunity.

I also want to point out that this policy is not what companies want. They want the removal of sponsorship requirements and quotas. They generally want to be free to hire who they want.
