Literally every level of wealth you go up (to a point) you will see the level of money/resources spent on schooling go up on average.
Here is a rough chart.
You have the poor people making under 30k a year that generally don't give af about school or if they do care they don't have enough info regarding school to really help the kids get the most out of their education. Their guidance usually begins and ends with "study more or I will beat your ***"
Then you have the lower middle class people making like 30-100k that know enough about school to help their kids do their homework and talk to the teachers to find out how they can help their kids more. Maybe they will scrape together money for a cheap tutor(maybe a high school kid or at best a college kid from a local decent school to help them with a class they are really struggling in. They will buy their kids princeton review SAT prep textbooks.
Then you have middle class people making 100k-500k that will send the kids to an SAT prep classes and hire good tutors(local HS teachers) for the core classes like math and English. They send their kids to either the elite public schools if they live in places like NJ or Mass. OR they send their kids to the good private schools that cost 20-30k a year.
Then you have the upper middle class guys making over 500k a year that are going to be hiring tutors(college professors) for every subject. They will be hiring 1on1 SAT tutors(not classes). The higher end people for this class even send their kids to elite prep high schools.
The rich doesn't even differ that much from the upper middle class guys, but they may or may not take it up a level. I know some that send their kids to public school. Some send their kids to Horace Mann. One guy has a English teacher at Columbia teaching his 4th grader how to write better. lol. Overall it is similar to the upper middle class level, but some may be hiring the best of the best for their child.
Obviously this is not set in stone. You have some billionaires that let their kids fvck around in HS because they are just going to work in the family business later in life. You have some middle class people breaking the bank to hire the best tutors for their kids. It depends, but it is a general guideline.
