Most jobs will give you a performance review and a raise every year to account for inflation and any increased duties you’ve taken on. We increase minimum wage by massive amounts after far too many years which causes all sorts of economic concerns, business complaints, and just a bunch of arguments everywhere. Shouldn’t they just increase minimum wage 3.5% or whatever, every single year?
Economists must think Belgium doesn’t exist. See this document explaining how automatic indexation happens for all Belgians (including those on pensions) without there being a higher inflation than in the other countries: https://www.abvv.be/sites/abvv/files/2023-01/Index_EN final.pdf A lot of it is: we simply get the raise a little quicker and without a fight, and only have to fight for real wage increases. Where in other countries they need to wait for the next wage negotiations and then fight to keep the real wage and hopefully increase it too.
Belgium is probably also macroeconomically insignificant in the euro zone
