Is it worthwhile for individuals to pay social security in full?

From the point of view of payment, it is a bit uneconomical, because there is a unit, and the full social security unit burden is 2/3, and the personal burden is 1/3. There is no unit or individual payment, and the social security fee is paid in full. From the perspective of providing for the aged, it is worthwhile to spend money to buy yourself a living guarantee for the aged. Of course, if you do nothing, have no income, or have a low income, just enough to survive, it is really difficult to get insurance. If you start your own business and earn considerable income, you'd better invest in labor insurance.
