What looks like is being imported is burdens on the welfare system rather than cheap labor.
A “guaranteed income” is a dole. That solves nothing, but exacerbates welfare problems. Other countries already do this, even if they do not admit it.
If you’re on the dole, you’re strongly discouraged from working — because most earned-income is clawed back, by reducing the dole. With a guaranteed annual income (or whatever name), every adult (i.e. no means testing) receives the same amount from the government. If you work, you take more home — less normal taxes.
End welfare as you know it. End minimum-wage laws. Simplify everything. Encourage working — don’t punish it. That’s what changing to a guaranteed annual income for everyone could do.
It’s not meant to be perfection — it would just be a lot better than the existing mess.
