Osteen has denied the money aspect of "prosperity" and said that prosperity to him is "God wants people to be blessed and healthy and have good relationships". We may still denounce that as too much of a "feel good" message, but it is basically an extension of the "abundant life" message even critics themselves teach.
Like this all too common sentiment:
the poor are fleeced of their limited resources because they are looking for an easy out from the life God has allowed or ordained them to have.
assigning some of the blame to the poor themselves, because their lack of prosperity is supposedly from God Himself and they want relief from it (which others take advantage of). Meanwhile, people teaching this, whether in books or from behind pulpits are usually prosperous themselves , or at least having their basic needs met, since that's the way churches and ministries are set up; figuring God has not "ordained"/"allowed" those things for them, or they are to be materially "rewarded" for their church/ministry "service". (With a couple scriptures cited to suggest that).
So it's like that same "prosperity gospel" is
only supposed to work for themselves; the leaders. Osteen and others' error then is extending this to the laity, whom God has supposedly assigned a lower standing.
So what ends up happening, is that the critics of prosperity holding these views, end up just as much focusing on a kind of "prosperity" message; as how can those poor deal with what God has "ordained" for them add find "peace"? That's when they start talking about "faith" and "victory" and "abundant life", and the "steps" to achieve those things. It then sounds a lot like the "faith" message, including if it doesn't work, then it's your own fault; you didn't do something right, such as not having enough "faith" (which is the dark side of this so-called "feel good" message; it's really not all "sunshine and a bowl of cherries", since nothing is ever as easy as "name it and claim it", though it sometimes looks like it in the proof-texts used to support it). The only difference with the critics, is that it's not about gaining money or health, but rather how to gain a proper "
attitude" to cope with the lack of those things.
Even some accused of "prosperity", such as Joyce Meyers, etc. are always talking about how God "brings" some disappointment to us to make us "grow" and develop the right attitude, in complete agreement with those criticizing them. (So again, it's not all "feel good", and we shouldn't generalize so much, especially when we're teaching ultimately many of the same things, in different ways. This, from the most "conservative" on down, such as the Biblical Counseling Movement, and the IFB types who say even the BCM has "compromised", etc. They all teach the same things about "attitude" and "steps to growth", making that the focus of "faith").
And as we see people using scripture's account of "suffering" to counter prosperity, but these are taken out of their original context of the actual persecution the early church faced (which is what the oft used scriptures are addressing) and applied to mundane economic and health problems people have today.
So we end up dismissing people's suffering, because "God ordained it" (and thus become like Job's friends), and then criticizing them for following leaders who promise it to them (in an "easier" way, because God wants it to be "hard", because "that's how we grow", which is more conventional 'practical' philosophy than any real sound biblical exposition). They will then more likely flock to those who say "no, God wants you happy and healthy now".
