The difference is that while the vote of each Californian might have less impact on the outcome of elections, there are so many of them that the problems that California has to deal with become important enough that politicians won't ignore them. If you make the situation work the other way around, then Wyoming's problems become even less important than they are right now and you can pretty much just ignore them and campaign in a certain county instead. If you don't handle people's problems then that makes them more likely to move, to seek a better future elsewhere.

Thanks for the thoughtful response. I can see how people would feel that way. Can also understand how people on the other side are frustrated when a minority of the population has disproportionate power though. So as with most things it sounds like there's no easy/perfect solution.
