Having worked at a JPMo competitor for several years, we did certainly value IT. At most such shops IT spend is around $3 Billion a year, so they're not messing around. Many even created specific dev centers around the world (i.e. London, Moscow, India, RTP, Dallas) specifically to do just dev.

But, the real kicker is at few such firms will you find the tech "talent." They might join mistakenly, but usually they'll get out within a year or two to better pastures at startups or SV. What often remains are the folks that are mainly task masters at CRUD forms, but not anyone that thinks about the merits of various architectures, reads up on optimal coding practices, or that learns in their free time. Nope, those are the high paid "contractors" that are hired when folks can't figure out why a six foot long query is running slowly.
