You are totally right that many of these problems are very difficult to solve. It's scary to put time and resources into things that may not work. We already are throwing so much money away into stopgap solutions though. The reason why I and many people feel frustrated with conservative policy is because it feels like they stall until we are forced into eventually doing "something" instead of implementing the full solution. Instead of saying, "hold on, do we really need this? Is this the best way to go about this?" it feels like conservative policy is to say "we will do everything we can to not spend money even if it is correct to do so." I totally get that this is a biased point of view. It's just an explanation as to why there is so much resentment of modern conservative politics.
