PROBLEM: (CNN) Germany's president Frank-Walter Steinmeier has warned of the fractures in its society -- highlighted by the electoral success of the far-right party Alternative for Germany (AfD) -- on the nation's Day of German Unity.
 Steinmeier  spoke of walls between cities and rural areas  between rich and poor  old and young  and online and offline communities.
They are "walls of alienation  frustration or anger" and behind those walls there is "deep mistrust of democracy and its representatives "  Steinmeier  said.
Without mentioning the AfD by  name  Steinmeier  warned that Germany's progress since 1990  becoming a democratic  peaceful and strong country at the heart of Europe  could be lost if politicians and ordinary Germans do not work together to fight the party's far-right ideology and to respond to the concerns of its supporters.
 Steinmeier  addressed this issue in  his  speech Tuesday  saying many Germans from the former East no longer feel at home in their own country  and question if anyone is looking out for them.
"This desire for a home  a homeland -- we mustn't leave that to the nationalists " said  Steinmeier .
"There must never be a route back to nationalism "  he  insisted  a statement that was met with a sustained ovation.
 Steinmeier  did  however  suggest Germany should consider stricter immigration controls in what can be seen as a bid to draw AfD voters back to the mainstream parties.
Germany should give asylum to those who are eligible   he  said  but must also consider "which forms of and how much immigration we want ... and need."
"Migration should be controlled according to our requirements "  he  continued  insisting that people who come to Germany must learn the language and abide by the country's laws and values. "That cannot be up for discussion."

SOLUTION: Frank-Walter Steinmeier

PROBLEM: That  in turn  led to attacks from fellow NBA star LeBron James against the commander-in-chief.
That policy did not stop  LeBron James  of the Cleveland Cavaliersfrom making it abundantly clear that they are unwilling to hear the president out  tweeting last week that the commander-in-chief is a âbumâ and noting that Curry told him that he did not intend to visit the White House anyway.
 James  also said  âGoing to the White House was a great honor until you showed up!â  referring to his meeting with former President Barack Obama.
U bum @StephenCurry30 already said he ain't going! So therefore ain't no invite. Going to White House was a great honor until you showed up! â LeBron James (@KingJames) September 23  2017
 James  voted for Hillary Clinton.
Obama invited  James  and then-President-elect Trump to the White House on the same day  November 10  2016.

SOLUTION: LeBron James

PROBLEM: But one of Silicon Valleyâs most influential billionaires  LinkedIn founder and Greylock Partners investor  Reid Hoffman   received  his  masters degree in philosophy from Oxford in 1993.  He  was originally planning to go into academia  but decided that  his  desire to do nothing less than change the world would be more likely in the world of tech. Thatâs not to say  however  that  he  abandoned the lessons  he  learned.
In an interview for Business Insiderâs podcast âSuccess! How I Did It â  he  explained that  his  unusual educational background has proven quite helpful throughout  his  career.
 Hoffman  told us  his  favorite philosophers are Aristotle  Friedrich Nietzsche  and Ludwig Wittgenstein  and  he  said that studying them has proven useful in two ways.
It honed  his  critical thinking
 Hoffman  said that âphilosophy is a study of how to think very clearly â and that is useful in both investing and being an entrepreneur  which  he  said is like being âan all-in investor.â
It gave  him  deep insight into human nature
 He  told us  âI think what every entrepreneur in consumer internet is doing is essentially embodying a theory of human nature as individuals and as a group for how theyâll react to the service  especially if itâs community or network properties  how theyâll interact with each other  how this will fit in their landscape of how they identify themselves and how they communicate or transact with other people.
 Hoffman  said in a recent episode of  his  podcast âMasters of Scaleâ that  he  considers the MBA path to be potentially dangerous for entrepreneurs  because it teaches them to approach business in a safe and ordered way; by studying the essence of human nature   he  explained in our interview   he  instead had an education into how humans interact with each other and the world â  his  business education came through trial-and-error in the real world.
âThereâs almost a sense in which part of being an entrepreneur or being an investor is being an applied philosopher or an applied anthropologist â  Hoffman  said.

SOLUTION:
Reid Hoffman
