Yep. Companies should be providing a flat $ amount per employee instead of %-based retirement system based on employee contributions.
My employer provides 5% regardless if you contribute or not. I was maxing my 457 prior to buying a home but dropped to 13.7% afterwards. As a Xennial with a decent salary in a HCOL area, 13.7% isn’t enough even with 5% on top of that.
On the investment topic, I wish I never put a penny in international mutual funds. Seeing little to no growth over the last few years compared to US investments is painful given my retirement funds are 15-20% international.
