How do they get rich?

Hi,

I sometimes see on TV people being interviewed saying that they have a 40M+, 60M+ etc salary and they have a very luxurious lifestyle.

I believe having such a high salary means the tax portion taken from it is 45%.

I was curious if there was any tax reduction that can be used at that high level that we don't have access to with a lower salary?

Basically, how can you become rich if you have to give away almost half your salary (more than half if you factor in the residence tax)?

Unfortunately, that's not a problem I'm close to having, it's just out of curiosity.
