DFW in the past 12 months has been clearing aircraft for takeoff before the preceding aircraft has even rotated down the runway. When they do this; I'd say we hit wake turbulence about 50% of the time; and putting in huge wing corrections low to the ground has always been frustrating. Well it happened again; and I'm going to start submitting reports every time now. We were cleared for takeoff a few seconds before the preceding E-175 had even rotated; and gave it about 5 seconds before we started the takeoff roll. At about 500 feet; we hit wake turbulence; which required near full-scale deflection to maintain aircraft control in the climb. We were still configured with flaps down but gear up. Wind was under 5 knots.Cause; ATC trying to get as many aircraft out of the airport in the shortest amount of legal time.Suggestions; bring back distance spacing; not just timing for aircraft separation.
B737-800 flight crew member reported encountering wake turbulence shortly after takeoff at DFW; and stated insufficient spacing was a contributing factor.
