Your comment is spot on. You're correct that traditional economics has focused on growth and consumption, and that this puts economic prosperity in direct conflict with sustainability and the health of the economy.
I tend to think that the answer isn't so much about specific laws (though the laws do need to change) as it is about holistic system change that stops focusing on working as much as possible and starts focusing on ways to optimize for human well being. This was supposed to be the goal of optimizing for growth, but we're seeing the limits to that thinking.
In response, new branches of economics have started that attempt to capture the frustrations many people have with the old ways, and find more holistic, sustainable solutions to economic issues.
One movement I have been following lately is just called "New Economics", and that search term will lead to a load of resources covering the issues being discussed by the New Economics Movement.
I've been tuned in to videos by the New Economics Coalition[1] now, who recently hosted a conference called commonbound. A central theme of New Economics is the idea that we should hold more value in commons, at a local level. Doing so leads to business decisions that are more likely to consider the people they impact. This doesn't work for everything (massive industry like aircraft production, etc), but it can improve life in a lot of areas. It is also stressed that people who work more use more resources (fast food vs cooking at home, etc) which is bad for the environment, and that working less allows us more time to spend with family and friends which leads to more happiness than just having more stuff.
A few people to follow are Juliet Schor [2] and Gar Alperovitz [3]. I also discovered the Institute for Local Self Reliance [4] yesterday, which is worth checking out.
What I've been working to do is reconcile progressive ideas for how I feel the world ought to be with anarchist/libertarian ideas that we shouldn't force anyone to behave a certain way. I think the classical liberal way of choosing how things should be and forcing everyone to comply is a recipe for inequality, concentration of power, and disenfranchisement of the people. To me, New Economics seems like a way to respect individual autonomy while creating an economic system that works for everyone.
This is a lot of links. If you want a short intro, something like this video with Juliet Schor may be a good start [5].
