Also a thing is that you'll like begging for love when you're just going to marry for money. Well, as they say it is just being practical but that practicality will make you suffer emotionally and mentally.
Even if you're that rich but you're not in loved with the person you chose as your partner. At the end of the day, you'll still find for that true love, no riches, no material things, just pure love.
So, it's not about true love all the time, something triggers union, and there are some who started with true love but didn't make the marriage work out in the end, so what's the point? Money or no money, once she's ready to be with you sincerely, it's good and money is not the sole judge of whether she will be with you or not, just the same way money could cause her to be with you forever as well. It's all about something triggering it and both parties helping it to work out.
And if you must know, money buys loyalty, it could be in a relationship or otherwise, and when the money stops flowing, the loyalty may end depending on the relationship they built afterwards. This is practical all around us, the lifestyles of celebrities and politicians should be enough to tell you this.
