There are evidence. A lot of evidence. Any country where the minimum wage was raised significantly, even if most of the time, it’s the private enterprises which end up paying those workers, we can see a boost of the GDP, which is the metric usually used to measure the consumption (and therefore production) of a country, considering something like 70% of the GDP is direct consumption (don’t remember the exact stat). The simple reason behind it is that if you give people money, they will spend it, paying the companies and people making the stuff so they can make more stuff. How can you except products to be sold if nobody has the money to buy it? And considering a lot of people talk about the price rise and hot having the money to pay this or that, it becomes basic logic, at this point.
