You don't care about their lives, as was made abundantly clear on wikipedia.
This guy clearly doesn't understand how Wikipedia works. When a sentence is contested people pile in with more detail and citations. He claims this detail and the citations are evidence of a conspiracy to make more of the nuclear disaster than he feels is warranted, when in fact they are simply a reaction to people adding  tags.
The problem is the other 400,000 who will rightfully say that their losses were so much worse, that they should easily be entitled to get even more money.
Let me explain the current situation to you, then perhaps you would understand why it is such a big deal for those affected.
Victims of the tsunami lost entire towns, but they are now being rebuilt. It was a natural disaster, no-one was to blame in most cases. You can point to specific examples of where people made mistakes, and in those cases there have been calls for compensation. For the most part though every reasonable effort was taken to protect those towns from known dangers.
In the case of Fukushima it is very clearly TEPCO who were to blame. They knew of weaknesses at the plant. They screwed up handling the disaster and made it worse. They have been dragging their feet over decontamination and compensation. Unlike victims of the tsunami those affected by Fukushima need to claim money from TEPCO rather than receive what amounts to welfare from the government. Plus most of them are still alive to claim that compensation. Unlike tsunami victims insurance won't pay out because TEPCO was to blame and some of the land and material in the exclusion zone may yet be salvaged. The tsunami is well understood and information is available, while TEPCO is still trying to keep a lid on things at Fukushima to prevent compensation payments from rising.
Both groups of people are suffering and both have genuine grievances. Trying to compare them directly or set them up opposing each other to make your point doesn't work and doesn't make things any better on either side.
