Fear not! Sure enough data-mining technologies and techniques by employers and insurers will, and do, lead to the scrutiny you fear, even now. However, transparency works both ways, and so too accountability?
In an evolving global social community, it will thus become immediately transparent that these HR policies promote employment of drone ants for factories, creative pragmatists for R&D, and Self-serving psycho’s for CEO’s?
This greater transparency will provide yet greater accountability, scrutiny and legislation for equality, act against social and biological prejudice?
I do share your concerns where healthcare insurance scrutiny is concerned, yet it takes only days for legislation to be installed to overturn unfair discrimination, IF? that is what society, peoples and democracy demands?
I envisage that data-mining, info sharing, transparency, and accountability will promote ebb and flow, (push & shove), of global social evolution and further democratic progress, ultimately?
