I don't think this is true in the long run, any more than genes which favor their propagation are bad in the long run. In the short term, viruses, cancers, shitty memes, doomsday cults and other low-sophistication replicators are favored.

But long term you get things like multicellularity, complex nervous systems, the scientific method, civilization and art. The road may be rocky but I see no reason for it to be any different here.

It's "bad" for us as individuals with our cultural background. It's not necessarily "bad" for the memes themselves, especially since the ultimate score in this game is to have an entire civilization proactively spreading the meme to others. Christianity, Islam, and other proselytizing religions are a good example.

I suspect that the old, successful memes are good for their hosts by many definitions of good.
