Is this meant to say 1,500,000 euros? 150,000 euros is ~$175k USD and the average US home price is currently sitting around $500k for reference.

edit: it does appear that 150,000 is correct, but it is an additional 0.1% tax on wealth above 150,000 euros.

Still basically nothing for the overwhelming majority of people. An additional $1,000 a year for every $1,000,000 you are worth.
