True equality is equal opportunity. Diversity will come naturally if there is equal opportunity.
Instead of DEI, policies and hiring practices should ensure that there are no racial, gender or religious hurdles that would prevent someone from getting a job, going to school, etc as long as they are qualified.
The other big flaw with DEI is blaming racism on the lack of diversity in certain fields when a lot of time it’s simply cultural differences. Women are overwhelmingly nurses but as long as men have the same opportunity, that’s all that matters. If it skews more women and the hiring practices is neutral, that’s just how the chips fell.
In some cases, you might find some jobs like firefighters are overwhelming white males. In this case, make sure your policies aren’t skewed to white men and then simply host job fairs and promote yourself to other communities as a career option and get them interested.
DEI is fine but it needs to come naturally and there are ways to do that.
