Mahatma, you sound as if you are judging the past by the standards of the present. Much has changed since then, not all of it for the better - the country has lost much of its industry for a start and gained many economic migrants.
There is a saying that hindsight is an exact science and it is but it does not and can not change the past. The country was recovering from a war, living conditions were far from ideal but the races did get along and work together. The operative word there is work, those that didn't were looked down on by everyone, also there wasn't the professional 'I'm offended' clique that we have today.
So, unless you actually lived and worked at that time your comment doesn't carry much weight.
