But reducing the work week only impacts the employer's profit via slightly decreased productivity. On the other hand with 3 free days per week you'd be more likely to put more money back into the economy.
The problem is today's balance of productivity vs. wage is only perfect for the employer and not much else is taken into consideration. What kind of bargaining power do employees have to change this?
Can price drops be forced on things that are in very limited supply, like homes in coveted areas? Or even on products or services that already have very low margins? Would the seller be there next year to tell you how it went?
The technicalities of forcing a price drop feel out of reach while shortening the work week has been done successfully twice already just in the past 100 years. Profitability is still higher than ever.
I get that that other costs (healthcare, education, housing) have risen so much that the cheap goods can't offset them. But, it seems that every little bit would still help, even if things were net-worse.
