Marrying with/without being settled

It means if I’m jobless then i should marry and if still not get money then go for 2nd one and then 3rd at least someone will bring money …
yes this example is an Islamic example & I m not neglecting it but there were different times/situations and if we start applying everything in our current situation then it will be hard to live…
If you talk about Islam then you know what Islam says? Its Husband duty to earn money for the Wife even this is not duty of wife to do khidmat (service) of boy parents. So what you think if a guys doing nothing and get married with a rich girl to fetch him and his parents as well then is it Islamic approach ???
