Employers can not hire you for just about any reason by stating something other than the real reason. If they put that down as a reason you may have a case against them but hard to prove.
The first part of the above is correct. The second isn't. Discrimination is not illegal. Discrimination for certain things, in certain situations is illegal. Most noteably...discrim for age, race, religion, origin are generally illegal. However, discrimination for financial reasons is specifically allowed. And to be clear...they aren't even really discriminating against you purely financially in this case..they are more saying that your judgment and planning are shown to be lacking, and that is, absolutely reasonably, not someone they want to employee.

To employ a person to perform duties specified by the employer.
No law requires that. Employers all hire who they wish. For the 25% of US employers large enough to be subject to the 1964 Civil Rights Act, there must be no evidence that hiring reflects discrimination by race, sex, religion age or disability. For jobs requiring high levels of education, an employer may have an all-White workforce, while giving no evidence of illegal discrimination.
