This is a question of priorities. Identify a problem, decide to fix it, then execute. It isn't about the particular solutions. Australia's gun control would not translate to a country like the USA and perhaps neither would its health care. First decide to put a person on the moon. Then execute. Only one country did that. It isn't that they can't solve problems like school shootings or affordable healthcare. There is no real will to do so. Not sure why exactly. It is a very strange place that defies expectations of how a developed country would behave.
