These prices for those who have money but do not have time for thinking and planning. The most unreal estimation is for tournaments. Just look at this, for 11 years old kid who lives in SoCal:
"Tournaments - $7,500 = 15 x $500 (some tournaments require farther stays and duration)."
It is completely wrong estimation. There are a lot of tournaments in SoCal. Fee is about $40 for singles. Plus money for gas, may be $10-20. That's it. Total sum is about $600 for an year, not $7500.
Why do you need to travel with 11 years old kid for tournaments? Only if you like traveling
