I think that things in NK have also gotten better if one compares it to the 1990s famine there. At least they're not starving anymore, right?
If you look at it that way then sure, but I tend to be very wary of attributing famine to the machinations of any government or regime since famines are often multifactorial and a large number of the factors are simply beyond human control (like droughts) or are at times beyond the control of the government whose population is unfortunately afflicted by it (for instance war or blockade affecting food supply). Government incompetence or capriciousness almost invariably plays some role but how large a role depends on each instance.
In any case the North Korean famine of the 1990s mostly occurred under Kim Jong-il (the second North Korean leader), not Kim il-Sung (since Kim il-Sung died in 1994 after all) and I would say the 1990s are a lot closer in time to today than the 1990s were to the start of North Korea's regime. This then would be an example of where things got worse for the average citizen over time from say the 1950s to the 1990s.
