My son is in university completing a 4-year bachelor's degree, and we are covering the tuition fees. However, at the end of this phase, he wants to specialize as a doctor, which exceeds our financial capacity. My son has two options: either to join the American Army, which covers all expenses, and upon graduating as a dentist, he works with them as a doctor without ever going to war, or the second option: my son takes a student loan from the bank ranging from $300,000 to $800,000 for his studies, and this amount varies from university to university depending on which university accepts him. What is the right opinion and what is the solution?
