I believe government price regulation is limited only to some goods and not all item's price is regulated by the government. Items that are non-essential consumer goods like clothing and electronics pricing, I think are not regulated by the government since they are purchased individually for personal use and not for production.
Governments may intervene only on raw materials and not into value added products. For example, cotton is a raw material where governments may fix a price for one ton of cotton whereas the denim cloth (a value added thing) which is produced from the same cotton will not have any intervention from the government on fixing its price. Yeah, governments also must be having some price strategy but I agree this strategy cannot be same for all the countries.
If you want to build a business this can help you dictate a pricing point for your goods or services and as a consumer this might help you be more responsible in buying.
Yeah, having a pricing strategy will help all of us. Both consumer and producer must focus on quality of the product to justify its price; due to this reason, we are seeing people are ready to pay higher price for known brands.
