I didn't watch the video but Is it getting worse under Biden? Obviously something needs to be done here.
Bidens border policy is definitely less hard-line than Trumps.
One thing the left in Australia worked out over a decade and a half ago is that the right-wing hard-border controls actually work, so on that issue the right and left here are in agreement in bipartisan support... But still seems to be divisive issue in the USA.
The USA will work it out at some point.
I can't speak to Australia, but I've seen little evidence of any significant benefit to be gained by the type of border measures implemented by the American Right. There is significant value in improving our points of entry, because this is where the majority of contraband crosses the border, but the right doesn't really focus on this issue.
