I think the first step is to have a meeting with all the women
And ask them their views
then is to ask the producers of their movies to pay them equally based on their scenes / songs
A superstar or SRK OR Aamir's caliber can do a lot to change the wage gap
They need to understand that tomorrow their daughters / women in their family will be on the industry too and it's not okay to convey the message "you are less than men
I'm not saying anything about salman since he doesn't have children
What do you guys think ?
