"societal change is inevitable, that does not mean its outcomes will always be positive" - I agree with this comment completely, Mrkim. The difficult part is obviously in achieving the good changes while avoiding the negative ones. I would hope that you would view equal opportunity for education, healthcare and employment regardless of skin colour as a positive change (and I don't mean forced equalisation of racial mix). In my current role I work with a number of South African emigrants and I think South Africa is another example of significant social changes having a negative impact as well as a positive one. The crime rates in South Africa have risen dramatically since the ending of the apartheid regime, as have job losses due to loss of investment funding, educational standards have dropped, etc. That doesn't mean it was right that there was forced segregation based on skin colour though.
