CarMax Require Such A Large Deposit

I want to know why the people over at CarMax require such a large deposit from their customers because it does not make sense to me at all.

They seemed to have wrecked my wishes of having a vehicle that would be able to take me to work. I have been out of work, and it is mainly because I do not have a vehicle. I think that something should be done about this at the soonest.

I am so annoyed at CarMax, and I feel as if they have no consideration for other people if you ask me.
