I live in Austria (big corp) and make 1x € a year.
My brother lives in Swizerland (big corp too) and he makes 3x € a year. It's a usualy saying here, that you make around 3 times the money in Switzerland compared to Austria, independently of what you work.
BUT:
In proportion to buying power and minus cost of living he has just about 1,5x € more money to blow (or to safe). Not 3x
AND,
he also says quality of life is 10x better in Austria: Do you live to work or work to live?
Spoiler: He's moving back to Austria in 1-2 years.
