You can't
possibly be serious with this bullshit.
I've criticized Sanders' character myself pretty vehemently in prior threads, and I stand by those points, but his policy proposals are
exactly the "10-year plan" you're suggesting he hasn't provided, and it's almost entirely aimed at improving matters for the working and middle classes, and providing more security and support for them.
https://berniesanders.com/issues/
Safe, protected immigration? Benefits everyone, reduces anxiety about family immigration.
Medicare for all? Vastly expands support and protection for the working and middle class.
Green new deal? Puts corporations to task for damaging the environment, pushes economic growth in new green industry that will employ more people, etc.
College for all, benefits the working and middle classes and eases financial woes.
Workplace democracy, entirely about improving working conditions and representation for working-class and middle-class workers.
Expand social security, which protects those who needs it.
Housing for all, which will further shore up protections for those in need.
Free child care and Pre-K for all, again, helps those who can't currently afford it or who have it put strain on their finances.
And so on. Every single
fuckingentry is about easing the fears of constant upheaval of the working- and middle-classes. Where the hell are you pulling your information from that you're not aware of this? It's not like it's hidden.
