How does a point load spread on a foundation wall?

Does a point load spread 45 degrees on a concrete foundation wall?

Example: if a wall is 12”wide by 8 feet tall,

By the time the load reaches the bottom of wall/ soil traveling at a 45 degree angle, is the bearing area 8sf for the load? At 3000psf soil
Can we then apply a load of up to 8x3000 (24,000lb)?

With this logic if the wall were only four feet tall, would the load going out in a 45 degree angle only achieve a 4sf bearing area thus making the load able to be a max of 4x3000 (12,000lb)

Also, does a running bond cmu behave the same as poured concrete?

Thanks!

Canadian Code says concentrated point loads distribute at 2 vertical to 1 horizontal. I believe grout filled masonry is 45 degrees. Obviously the bearing pressure would vary depending on how close the point load is to the edge of the wall and how close the next adjacent point load is.
