There are only 3 ways to lower(that came to my mind) prices in a quick way.
1: Abandon regulations. If corporations don’t have to invest into safety, ecology and such stuff they have lower production costs which can mean lower prices.
2: More competition. If corporations have to compete with each other they usually start a battle over who gets the best quality for the lowest price.
3: Subsidies. Nothing to say here I guess.
Edit: Point one and three lower production costs. As others have already pointed out, these dont mean lower prices, but more profit for companys
Youre right. I forgot that companies will likely not lower the prices.
