Then they have options which don’t involve removing a newborn from its mother: adopt a newborn from a country where healthy newborns (with non drug addict parents) are regularly put up for adoption. There are plenty of them.
This used to be what celebs did. Angelina Jolie adopted from Cambodia, Vietnam and Ethiopia. Madonna adopted from Malawi. Julie Andrews adopted from Vietnam. Emma Thompson adopted from Rwanda. Katherine Heigl adopted from South Korea. Meg Ryan adopted from China.
But international adoptions have dropped massively in the last 20 years. Ethiopia, South Korea, Romania, Russia, China, Guatemala and Kazakhstan all banned or cut back on international adoptions. It has a lot to do with politics, bad publicity and not wanting to be seen as a poor country which exports children, concerns about exploiting poverty stricken birth mothers and removing children from their birth culture.
So as a result of reduced availability of healthy children from other countries, people are using surrogacy as an alternative route to get healthy children.
