Politicians and newspapers that condemn immigrants and Muslims for "flooding" the country are full of praise for the Dream speech, to the extent you need to check you heard it right, as maybe he said: "I have seen the promised land, and there's no bloody Bulgarians in it for a start".
Maybe David Cameron's praise for Dr King has signalled a change in direction for the Government. Because Dr King didn't just speak about segregation, he saw it as part of "the evil triplets of materialism, militarism and racism" and, giving his reasons for opposing the war in Vietnam, said: "We must deal with the deadly Western arrogance that has poisoned the international atmosphere for so long".
So it could be a surprise when the British Prime Minister starts a speech about Syria saying, "We can condemn Assad all we like, but the underlying problem is deadly Western arrogance. I've told Mr Obama, and he spoke at Dr King's memorial march so I'm sure he agrees".
Then the politicians around the world who admire King so much might adopt his attitude towards the economy.
This didn't happen at the memorial, at which business leaders spoke, and it was sponsored by a company called BTC Consulting. Maybe they arranged a slogan for the march - "Now your rights are made civil we'll make consulting bills shrivel".
It's a shame they didn't exploit other sponsorship opportunities, such as getting Kevin Bacon to make a speech that went: "I too have a dream, of a day when children won't be judged by the colour of their skin, but by the content of their superfast 4G mobile phone, because I may not get there with you, but one day EE will have us ALL connected."
But the adoration of banks and big business displayed by most Western governments may not fit exactly with the attitude of their hero. For example, he said: "A true revolution of values will soon look uneasily on the glaring contrast of poverty and wealth. With righteous indignation, it will see individual capitalists taking profits with no concern for social betterment, and say: 'This is not just'."
If you look carefully, you may spot a subtle difference between that and the policies of George Osborne, Britain's Chancellor of the Exchequer. The other side to the speech that can get lost is that Dr King wasn't just hoping for a world in which people were nicer, he was calling for a movement of millions that would force change in the system. He didn't say he had a dream and it made him feel really chilled, and if anyone else gets stressed about the Ku Klux Klan or not being allowed on the same street as white people they should try dreaming and the tension will simply melt away. He asked his followers to "go back to Mississippi, go back to Birmingham", and bring about change.
To many this must have seemed an impossible task, given the violence of those who disagreed. The Southern police protected segregationist killers, and the FBI called King "the most dangerous man in America". (Now they'll assure us they only kept him under constant surveillance as they adored him, and didn't want to miss a word of his inspiring rhetoric).
Maybe what the 50th anniversary of Martin Luther King's speech reveals is that politicians are marvellous at standing up against injustice, as long as it was 50 years ago. Ask any political figure about the Spanish Inquisition and they'll be completely against it. It's only when it's happening now it gets tricky for them. Maybe they're so overworked, they're always 50 years behind.
