You do understand that the TSP pretty much IS your retirement?
Still, posting the “government (i.e. taxpayer) contributions” is a good idea.
No, it isn't. Under FERS, there are three separate retirement funds; TSP is one of them and is completely voluntary. The second leg is social security, the third leg is the actual government provided retirement plan that I pay a pittance into. That's the fund they're talking about increasing contributions for.
