Along those lines if someone hypothetically doesn't see themselves doing 20+ years and would prefer government matches to contributions, is there any way they can opt into the new system?
Presumably, yes. If they let people who enlist within the next two years to choose between the two options, but not the people who are already in service and grandfathered into the legacy system, I'd be very surprised.
Dude, TSP isn't a benefit- anyone can invest in a retirement savings fund.
TSP has much lower fees than most 401(k) or IRA options. As it exists now, it's a benefit, just not a very good one. The addition of matching will certainly make it more competitive with what's offered in the private sector.
I'm aware of what the changes are. You previously said that a 4 and out servicemember left with nothing, which implies he couldn't invest in TSP. I just don't agree with that line of why the new system is better.
I think what he was getting at is that you don't get any more out of it than what you put into it (other than whatever your return is during that time).
I'm not smart at this kind of stuff. If the government paid people less retirement, would it free up dollars to pay future service members more active duty money?
It would, but I doubt it'll work that way (unless you count the matching contributions as extra pay). The whole point of this was to save money, because funding the pension obligations is a huge expense. It still will be, just less huge.
I'm just surprised it took them this long to implement matching on the mil side, civilian gov't employees in FERS have had it for a while. I certainly hope they'll match Roth contributions, because it doesn't make a whole lot of sense for me at this point to make traditional contributions instead, when my marginal tax rate is probably the lowest it's ever gonna be while I'm working.
