Why is it always to short to reach the power socket?

3 Tv's wall mounted over the last Month and all of them don't reach the power socket just above the skirting board FFS ! I'm not mounting the TV's 10 feet up the wall either. I know in new build houses and house rewiring the sockets are mounted higher up the wall to accomodate the disabled (25th electrical edition or whatever the fuck were on now! ) but come on manufacturers, make the power leads a little fucking longer.
