Of course inequalities remain, always have and always will. As long as their limited resources how do propose that everyone gets the same?I don't really like the product of his time argument. This is still that time. Racial opression still exists. If anything these people were responsible for ensuring that that time began or extended it through their racist views. Those systems that they helped to create/instill/continue still remain today. Racism, racial inequality and opression still remains today. Also, not everyone was racist at the time as said above or believed in these types of things. The people with the power did which is why slavery and racism existed to the extent that it did but did that make it okay to be racist? Of course not. Racism has never been okay. By throwing out buzz phrases like product of his time it's almost as if you're putting a wall between now and then and acting like we are far far away from that time of thinking which is far from the truth and is shown in the inequalities that remain.
Discrimination comes in many form that so many people aren't aware of. As I said, I'm an Indian who did my PhD in Barcelona. I never faced any racism or discrimination during my my time there but once my PhD finished and I started looking for jobs in Europe, I found I'm not eligible to apply for so many jobs because those companies can't hire a non-EU citizen. I've had 3 interviews in the last couple of months where they told me that although I was among their top rated candidates the administrative procedures for employing a non-EU citizen are too time consuming or the salary requirements for that are beyond their means. Now is this not a form of discrimination?? Had I been a European I would have got those jobs. I'm essentially being punished for where I was born, something I have no control over it.
But I realize that it's not possible for everyone to be able to freely work or live everywhere. There are limited resources and all governments or leaders will naturally look after their own first. This same behaviour trickles down to society, that when a crisis approaches, people naturally fear another tribe taking over their resources and do everything in their power to prevent that.
We live in an age where resources are far plentiful than ever before, so there is less open strife and more scope for harmony. Churchill and his ilk were leaders at a time when resources were limited and their existence was threatened, they did what they believed was right to ensure the survival of their tribe. Was their behaviour terrible for others? Undoubtedly. But their priorities at that time were just their own tribe and not the others.
