If the salary are lower than before, the price of goods supposed not to be increasing. What I noticed in almost all countries, as the price of goods and services are increasing, the salary also will increase in such a way that everything will balanced, but the government do the manipulation for their own good.
In poor countries, it doesn't work that way. Usually, product and service prices go significantly up and salaries stay the same or in some of the worst circumstances, they might get lower. For example, salary in informational technology in my country is going significantly down because there are too many software developers locally and competition is very high. Inflation is super high and salaries of UI/UX designers and developers are going down. As soon as many local people start working online on websites like Upwork, that situation might be fixed but I am not sure. My family could buy more with 50% of our salary 7-8 years ago than it can buy today with 100% increased salary.
But the signals I've read here and there about the industries are better than in the last 2-3 years, quite some businesses seem to be recovering. And that would be the opposite of decline, even though it needs more time on this trend in order to gain the so needed confidence.
In my country, businesses are doing way better today than they were doing years ago but their appetite went up and they want to keep as much profit as possible. I mean that if business owner is a pig, even if it recovers, it wont care about employees because it senses that profit is increasing and his own appetite should grow big.
