Why doesn't anyone care about usury anymore?

I get that Christians aren't necessarily bound by all the OT laws, but usury was considered a sin up until relatively recent times. What's changed? Charging interest on loans is so utterly commonplace that it's just seen as a given - why aren't there Christian-driven political movements against it as with other sins? Is it ever preached about in your church? Are you personally opposed to it, or consider it a sin/immoral?
