In a vacuum, it might be a perfectly fine way of fulfilling the need of being a parent – & benefiting another who made the choice to be a surrogate without any coercion.
However, given extreme inequality being wealthy western prospective parents & surrogate mothers in the Global South, I think that poor economic conditions can do the coercion without the involvement of anyone else.
I don’t say this with the intention of banning the practice, but so that awareness of the inherent imbalance in power can lead to people factoring the ethical issues of the situation when deliberating about how to become a parent. They’d be asking someone to go through a pregnancy and giving up a baby (very difficult, even if one isn’t able to parent properly in their circumstances) who easily would not of their own accord go through such a serious, monumental undertaking. Surrogate mothers do have their own agency regardless of circumstance, but their agency is much restricted due to having to somehow deal with challenging circumstances. Their range of options relative to what – in a vacuum or with more circumstantial freedom – they’d be willing to put up with is much less than those of western prospective parents. This means they’re vulnerable, & this is being exploited in order to benefit incredibly advantaged people. At the very least there needs to be steps taken to counteract the difficulties this could cause surrogate mothers, & to hold those with more power over the situation accountable to ensure the mothers themselves feel they’re treated very well.
Then, factor in how unethical some operations are that facilitate tourist surrogacy. Some essentially keep women prisoners for the duration of the pregnancy, ostensibly to ensure they receive proper medical treatment. Physically well cared for prisoners, but not under conditions most people would willingly endure unless their other options made them desperate. This does somewhat involve taking advantage of the vulnerability of others. But they’re more than walking wombs, & treating people’s liberty as much less worthwhile concern than that of the most stringent prospective parents is unethical.
I’m not sure if it’s mentioned in the article, but there’s so many children who desperately need loving families. Yes, I understand wanting a baby as opposed to an older child, but if one’s willing to go through the lengths involved with reproductive tourism, I hope they seriously considered adoption (I know it’s a very difficult process, financially, emotionally & in terms of time and bureaucratic hassles. But it’s also not an easy thing for a child to go through the foster care system.)
There’s also environmental concerns regarding population. People living in the US consume, on average, 4X more resources than at least those in the global south, & I’m sure everyone’s aware of how limited our planets resources might be for those already living. It shouldn’t be the burden of those with fertility difficulties to lower our birthrate by forced adoption, yet everyone should at least consider doing what they can to keep from avoidably worsening major problems facing our whole species.
