It’s a warning about how deluding leftiness can be.
The idea is that you rob Peter to pay Paul and keep a commission on it, and you leave Peter to fend for himself before God.
You can get some simulacrum of life that way (due to the overflowing grace of God making up for some of the colossal waste) but never a true full-on blessing to the maximum of which earth is capable.
