Ah! Here is where it gets interesting.
In Canada, CPP (Canada Pension Plan) and EI are funded by a tax on employee labour. Employer + Employee funded. They are not considered to be social welfare systems, but pay-in systems. Ok, mandatory but funds are (should be) stand alone for only that purpose. There is some politic-ing around how EI is paid out, as it is different by region, but generally it is pay-in, earn your credits, pay out insurance if needed. (yes, i am ignoring a few facts here about what really happens)
US social security is funded by general revenues and not really a pay in system, i think.
Canadian "Welfare" programs include provincial assistance (traditional welfare), federal low income support for families, old age security, disability assistance (a part of the provincial assistance) and a variety of tax benefits and back to work programs for disability or very low income.
The CERB payment of $2000/mo is true "welfare" except for those that qualify under traditional EI benefits.
