As much as I have my issues with Judaism one good thing to say about it was the approach of Rav Hirsch to influence the idea that Orthodox Jews can involve themselves like normal people in the secular world. You come across a lot of Orthodox Jews in many top universities who work in science or mathematics or medicine.
I live in an Orthodox Jewish community. So many of these Jews have achieved great things in their lives. Many of them are enterpreneurs, capitalists, work in business, or make a lot of money, and just in general know how to navigate around in the world. I personally know several millionaires some of whom I am friends with. I have respect for these people, as they achieved something in their lives. But every single one of these Juden fit into the description of being im Derech Eretz.
In my graduating class there were some yeshivish boys. Who did not go to college, who did not get a job, but instead are still learning in Israel or where ever it is where they are learning. It has been years already and they achieved absolutely nothing in their lives. When they get married they will not need a way to support themselves. Their rich parents, who have achieved success, will simply support them. I have no respect for these kinds of Jews. They have wasted their lives entirely. They consume and do not produce anything of value. They are a waste of a species and any human talent.
Maybe I am wrong on this but it seems as if the idea of Torah im Derech Eretz is losing popularity in Judaism. As the current generation can live off their parents and then move to Lakewood (Israel). This was not something that was possible 50 years ago and hence the popularity of being yeshivish is growing in the Orthodox world. Yeshivishness is a disease that will retard the Orthodox Jewish world back to the bronze-age (at least Hirsch was open-minded enough to consider the theory of evolution as a possibly true theory and he was alive right at the time of Charles Darwin).
However, there are good news. Orthodox kids are leaving Orthodox Judaism at the faster rate than ever before. So maybe the fact that Orthodox Jews are moving back to yeshivish is not a big deal as it is much more likely they will simply leave Orthodoxy.
