Grant amnesty to every illegal immigrant
Again, the same issue comes to play in the opposite direction. If a President, like President Obama, wanted to legalize a large swathe of illegal immigrants he would not be allowed to. The President still needs support from the SCOTUS, and that wouldn’t happen.
Stop social security payments
The 2016 election cycle was crazy and even crazier was the idea that somehow certain candidates would disband social security and halt future payments. Social security is slated to go until nearly 2035 before any adjustments have to be made. Just like workmans comp, social security is your right and you’ve paid into it.
