Japan: Tsunami anniersary what has changed? What was learned?

Today 2 years ago was the great Tsunami in Japan as well as a massive earthquake. To the tens of thousands dead RIP. Now we still haven't raised the sea walls which is disgraceful. And Money raised for victims made homeless has been squandered on field trips to Japan for rich New Yorkers' children. People sleep in gyms, and American kids are staying in the nicest hotels in Japan and traveling around on a private tour bus. The PR to mend tourism is more important that the actual homeless victims of the tsunami. No fundamental changes in prevention, and no one is in jail for removing warnings in reports from seismologists to TEPCO's reports. And currently the piping at the plant in Fukushima is being run shoddy hiring mafia workers and other expendables. Reflection for the thousand of dead but also some sober thinking about all of the human ends pre and post disaster which remain unaccountable and irresponsible all in the name of saving face. The world suffers from severe political ignorance and apathy. Bring any of it up though and you'll be accused of throwing mud in the face of the victims. Everything is completely backwards.
