The most successful (but still crappy) solution to this that I have seen is developers undertaking guerilla tech debt work. This can be done by bundling maintenance work into an existing task where the two are actually not that related or by simply carving out bits of time between official tasks.

While it "works" it is certainly not ideal that people have to go off the reservation to ensure that the project doesn't implode in the future due to the accumulation of buggy code, performance problems and likely security vulnerabilities.
