Similar "easy solutions" exist for: the obsesity crisis (eat less); climate change (burn less, switch away from beef, use less cement, steel, aluminium); gambling, tobacco, and other addictions (just stop); dishonest politicians (just don't vote for them); heart disease (exercise more, eat vegetables); and poverty (spend less/earn more).

Notice how the "easy solutions" don't generally get followed? That means they're not actually easy solutions, they're short glib answers that miss how the problem became a problem in the first place.
