McWho, shouldn't you have been asking these questions and doing these calculations before you embarked on this career path.
The sad fact is that the financial numbers simply do not work out for many students. Many would only be able to service their loans in the best case scenario of getting a good flying job immediately. Most will not get a flying job immediately, many never will at all. Many will go bankrupt, many will have to return to their previous jobs to pay for the qualifications that they will therefore be unable to use. Many of those who do get pilot 'jobs' will be living in effective poverty for many years. the Flying school brochure cover lifestyle is not a reality for the vast majority who apply to the schools.
This is a matter of due diligence which you should probably have done earlier, but you are certainly not alone. Virtually nobody seeks out the bad news, even though it would save them much pain later.
