I was writing mean rates, not marignal.
For 300K in CA:
- marginal is 35% federal, 9.3% state, 2.35% FICA
- mean is 24.74% federal and 8.06% state, 4.79% FICA.
> I can see that paying for 3 generations on one income can be hard.
Yes, most working class people have to care for 3 generations. Parents being wealthy enough to take care of their own retirement expenses is a small, small number. Working class people in their middle ages choosing to not have kids is also a small number.
Someone in the UK on £236K ($300K) currently takes home only 57%, and doesn't have access to 30 year fixed rate mortgage loans
