> Yes, a biased pipeline is absolutely something that needs to be solved.

No it doesn't. Bias isn't always bad or oppressive. It needs to be proven that the bias is "bad".

If rich kids are underrepresented in tech because their families have connections in finance and they tend to major in finance more often, is this a problem that needs to be solved?

Frat bros are underrepresented in engineering in tech atm.

HR, recruiting and hundreds of other job families and careers have "biased pipelines". Should resources be spent to solve all of them?

Why only tech?
