  Democracy functions of wavelet admissible bases are computed for weighted
Orlicz Spaces in terms of its fundamental function. In particular, we prove
that these bases are greedy if and only if the Orlicz space is a Lebesgue
space. Also, sharp embeddings for the approximation spaces are given in terms
of weighted discrete Lorentz spaces. For Lebesgue spaces the approximation
spaces are identified with weighted Besov spaces.
