The US then and now was totalitarian and authoritarian. Some of you, especially here on hn, may not fall into those mind-sets but it doesn't matter - you've lost - you're barely scraping by, working 60 to 80 hours a week and you have no time to change your environment. Meanwhile the political class is able to work full-time on perpetuating their power while taking away yours. You have no power, no rights, because they have been chiseled away the last 30 years by the authoritarians.
I've said this before and I'm always downvoted but I don't care. Just leave. Go to Berlin, or London (not much better though), Switzerland, or anywhere else. Even if you go to someplace like the UK that isn't much better than the u.s. you will at least no longer be contributing to a government spending 10X to 100X of any other country on arguably evil pursuits. Take your wealth-creation skills to somewhere else where you won't be contributing to your our demise.
I know that many of you will discount this one event as a one-off - MLK was certainly special. But it's only a one-off because it was the start of this sort of campaign against someone that can bring change.
