There's an old nugget that if anyone could time-travel they'd go back in time and kill Hitler. Nobody would go a few more years back to educate him.
People are not educated to look at the big picture but to react in the moment. Stop the theft as it's happening. Shoot. This goes best with societies where taking a life is considered appropriate response to someone trying to steal your fishing lure, societies where your individual rights trump absolutely anything else (imagine explicitly voting to pay more taxes yourself because that will benefit the poorer part of the population).
Reacting in the moment requires almost no thought out process. It's mostly autonomous, a reflex. Thinking of the bigger picture, identifying a root cause, identifying the impact of each of your options, these all take a strong enough education to override that reflex.
Thinking of bigger picture is all well and good, but the moment you mention education I cannot help, but chuckle. In the context of US, education already is.. lets call it overburdened. Maybe the solution is not to override the reflex, but to appropriately channel it.
For the record, I am just putting words together. It is late and infant does not want to sleep.
Ask you what your evidence is for that assertion given that crime rates vary so widely around the world for disparate reasons.
The prevalence and types of crimes committed really do vary widely as well (though its often hard to get a clear picture since different countries have different reporting mechanisms (or none at all)).
He read newspapers and pamphlets that published the thoughts of philosophers and theoreticians such as Houston Stewart Chamberlain, Charles Darwin, Friedrich Nietzsche, Gustave Le Bon and Arthur Schopenhauer. Georg Ritter von Schönerer became a major influence on Hitler. He also developed an admiration for Martin Luther. During his time in Vienna, he pursued a growing passion for architecture and music, attending ten performances of Lohengrin, his favourite Wagner opera.
It is a fallacy that murderous racists are simply uninformed, that they just weren't in school on that day in the fourth grade where your teacher tells you to be nice to people. Some of the authors he was acquainted with were vocally against anti-semitism. The most dangerous monsters are highly educated people.https://en.wikipedia.org/wiki/Houston_Stewart_Chamberlain

Hum, could I suggest an evil alternative? Just schedule a few meetings with the people that lend money to Hitler and explain them that he will try to keep the money and will go to extreme measures to avoid returning it, including killing them or their relatives if possible. Really bad investment, don't touch this turd with a thousand foot pole. Thank me later when you still own your castle in Europe.
Result: Hitler never climb in a position to became Hitler. Nobody dies, nobody needs to enter in a war to recover the investment and you don't became a murderer. Hollywood would be devastated for sure but, apart of this...everybody wins :-)
So maybe the person could go back in time and discuss with the negotiators at the Versailles treaty after the first world war. Or maybe try to inject some economics education to try to prevent the hyperinflation.
Room for some XKCD or SMBC comics!
But in any case yes, Pre-WW2 Germany was "a paradise" compared with Post-WW2 Germany or with immediately post-Hitler Europe if you prefer it. (And the world is much better without cocaine fueled dictators, for sure).
Taking a leaf from Deming, we have a system, a process, a society that creates a certain, relatively stable, number of criminals per year. Trying to address specific criminal acts or specific criminals is just meddling that can backlash as easily as it can help.
When you have a stable source of trouble, it makes no sense to try to fix individual occurrences. You have to address the problem at the source.
We have created this system! We can create something else if we're unhappy with it.
