Why is inclusion so difficult to achieve?

"Getting Serious about Diversity" contends that a business should be more than its bottom line; diversity cannot be simply a buzzword to prove that a person is hirable only insofar as they can "increas[e] the firm's profitability" (Ely & Thomas, 2020, p. 122). Instead, the authors propose that the loftier aspirations of personal agency and dignity should be goals enough. While speaking on biodiversity, Doyle addresses profitability in another way by assuring listeners that there is in fact a way to cut costs with biodiverse employees, while first implying it's still common practice to hire new employees rather than make adjustments for existing ones (McQuaid, 2021). Both mediums make strong and compelling cases for diversity and its many benefits yet feel obligated to justify themselves financially.

Do you think the main issue with inclusion boils down to money? What other factors impede diverse practices?
