The Agile Manifesto

    Individuals and interactions over processes and tools
    Working software over comprehensive documentation
    Customer collaboration over contract negotiation
    Responding to change over following a plan

There are many variations built on top of these, but without these it's not Agile.

None of these things makes management easier, you still need a good manager to make a project work.

Nothing in the manifesto says you should ignore technical debt, that is simply a choice your manager has decided to make. Its not the fault of Agile.
