If your ideal was realized- parity financially- you'd still have PLENTY of women forced by their financial situation to 'prostitute' themselves into marriage. You'd also have plenty with livable wages who'd try to marry up and STILL 'prostitute' themselves into marriage.
The real difference as I see it is currently more men are willing to 'pay' for such services than women. The way to equalize things is more likely to equalize the demand.
