The following chart was shown on a NHK programme on 31 Jan 2015 and apparently caused quite a "hoo-haa"... it claims "If you are born in a poor family, you life is basically finished." And it gives the path of two hypothetical persons:
Mr A: born in a family that earns 10 million yen a year (US$85,000). He will attend the top school, which results in him getting a good job with average 6 million yen average salary, have a good family with grandchildren, enough savings and lives in a up-market retirement home.
Mr B: born in a family that earns 2 million yen a year (US$17,500). He has no chance at a university education, will be doing odd jobs with an average annual salary of 2.25 million, no chance at getting married, and will spend his final years alone and poor.
Apparently, lots of comments (in Japanese) supporting the claim. Luckily, not so here it seems...
