25 days is the legal minimum. My employer gives 30 days paid vacation. Some companies also handle holiday pay slightly differently (while still complying with the law), so it's possible to get paid while you are on vacation - I did.

You have to have a lot of money before the wealth tax hits you, and it's quite low anyway (if you have enough money that the wealth tax will hit you, you can earn more in interest having the money sitting in a bank account than you will be paying).
