There is a good term in the USA describes them well - "gold diggers" and they know you have gold, and they want it.
Well they are doing it the hard way
I read each of their requirements and they speak rudimentary english and want men up to 60
They should take 80 year old understanding millionaires to get the statistics on their side
and early inheritance : but to be on the safe side they should ask 25% in dowry

Belgian taxpeople foresaw these golddiggers
If the wife is 20 years younger and married less then 5 years they do not inherit
The state tax gets the money
