About one in 10 are considering leaving their main job in the next six months and instead earning money from social media, e-commerce or trading platforms, according to a Morgan Stanley poll of 12,500 people.

"The received wisdom is that as COVID subsides, and with modest extra flexibility from employers, the majority of people will re-embrace their prior routines", a team of Morgan Stanley economists and equity analysts wrote in a note.

"Our data suggest otherwise."

"It reveals a far greater potential risk of structurally higher wages", Morgan Stanley wrote.
