Gala didn't have to strain herself too much doing that though, she was a living proof that success mostly is about "who you know" rather than "what you do" as she was already a well known socialite and had all the insight on those circles of rich people and gallery and museum circuits, that was already her lifestyle without Dalí, just hanging around people who might be influential for her own benefit and ego stroking.She was, she would find clients for him, read to him while he painted and basically be his tard-wrangler.
All Dalí had to do was be the face of the brand, say a few nonsensical words to strangers and maybe shit himself at times.
Really, sometimes artists wives were responsible for the husband's success, they would take jobs to keep the house on float, find clients and organize expositions. Most of the time, they'd throw their own dreams of being artists through the window so their autist husband would succeed.
In the case of Van Gogh, It was his brother Theo in spite of having a family of his own, and in Remedios Varo's, her husband was rich enough to pull her from her job as scientific illustrator and allow her to dedicate herself to art.
she also benefited a lot by milking Dali, she had a lot of expensive habits and sexual perversions, she fucked younger guys a lot and both had big and expensive orgies, their relation was of mutual leeching off each other, she was a severely vane woman who was obssesed with money , celebrity and everything that comes with it. She was already looking for her golden cow before Dali came along, just any stooge would have done the trick.
