I tend to wonder where your equating the "PWE" with money is coming from.
My real exposure to the PWE is in churches where, as soon as you set foot in the door, people had some class for you to attend, some committee for you to join, some children's event for you to help organize, etc. Just super-organized, very well-staffed, and highly volunteer-based activities and ministries within a congregation. Also -- and I suppose money comes in here, if at all -- the PWE was directly related to the tithe -- as in, you work hard to make money, and the most important part of that money-making process is the fact that ten percent comes right off the top and goes to the church...and in my mom's house, that was gross, not net.
The PWE seems to be so ubiquitous and touching all aspects of life because, in doing away with a liturgical calendar and holy days, there was more time to work. This desacramentalized life to a degree, as Gabriel said (and Fr. Stephen Freeman also has commented on this), but it can not be said that it completely divorced man from some sort of devotion to God. Following the industrial revolution and the protestantization of parts of the West, the offering that used to be one of time spent in the holy place doing the work of the people in ευχαριστια to God, was now one of legal tender in the collection plates that was the "new fruit" of the sweat of one's brow. Hardly as holistic (unless the worker had a tradition of prayer while working), but it surely makes for good, grassroots funding of church plants and missionary efforts independent of any state church funding. The PWE, in this case, was and is an example of the evangelical conviction that "if you want something funded and/or manned, you have to do it yourself."
I have to say, this is one of my biggest frustrations with Orthodoxy here in America (I have no idea what it's like in other countries; probably it's very different, as our American obsession with parachurch ministries is more than likely bizarre to other countries). We're small, mostly, because many folks are used to the state funding these massive buildings with breathtaking iconography. Stunning visually, but the fact is that many people in our OCA parish who immigrated here were shocked that the government wasn't funding our mission. That they should, themselves, take an active part in financial ownership and stewardship of the mission was completely lost on them (this is mostly why our priest of twenty-plus years is just now within reach of becoming full-time...enough folks who grew up tithing are now attending, so finances are for the first time making this really feasible).
Evangelical churches tend to grow, also, because as I said above, folks catch the spirit of volunteerism as soon as they walk through the door. Children's scripture memorization club once a week? The sign-up sheet for leaders is soon full. Choir? Same deal. Sunday school teachers for sixth grade, seventh grade, eighth grade, etc? Done and done. However, you walk into many Orthodox parishes, and it's...liturgy...and coffee hour. And while that's the indispensable core of our Faith, other ministries and spiritual gifts the Spirit's given to the faithful ought to flow from that core. Bible study leaders...church school teachers...men's and women's group coordinators...outreach organizers etc. We shouldn't just be "busy being busy," but didn't Christ "give gifts unto men" that some might be "apostles; and some, prophets; and some, evangelists; and some, pastors and teachers; For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ: Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ"?
It seems the recognition of lay roles within the life of a congregation is a very positive result of the PWE that, imo, the Orthodox could stand to learn from...not in blind imitation, mind you, but in a bearing of the fruit that faith, repentance, and Eucharist should naturally bear out. Forgive me if I've offended.
