The package TCU offers your kid (scholarships, grants, etc.) is the primary factor. Then all the secondary factors kick in - wealth, network, program, support system, etc. Picking a college is increasingly like buying a car. Different things (makes, models, packages, options, insurance and maintenance costs, brand, experience) make sense for different people and looking at one thing (ie wealth) isn’t always determinative.I also was accepted in 2003.
Back then, TCU was known for being a very cheap option for a private school.
Nowadays, it feels bad, but I don't recommend TCU to most people unless their families are very very wealthy (I'm talking 5-10M+ net worth) and well connected and they are just going to college to go to college. Otherwise there are better options where you will learn just as well and get a bigger network when you graduate. The "small class sizes" and "intimate" learning do not even remotely justify the cost difference. Employers don't care about many things less than how well you knew your professors.
