You own $10 of which the bank has custody. It's your property. Subject to certain defined rules, the bank must return it to you or transfer it to someone you authorize to get it, on demand.
With Socialist Insecurity, you own no part of the bogus "assets" of the nonexistent "trust fund". Nothing's yours, the $$$ you were forced to "contribute" is gone, & whatever you get is what Congress deigns to give you. it's a welfare transfer payment program with a dedicated tax, & a payout formula that has been based on past pay-ins.
The concept of rights & ownership is "all ideology" too if our masters can ignore them.
