Just like he can't deport 10 million illegals either.
The reason is simple math.
Current estimates are it will cost $10K to find, detain, process and deport one illegal.
For every employed illegal deported, his Trump voting employer will lose $1000's in productivity, income and other costs associated with finding and hiring a replacement. Since some illegals are not employed (wives, children, etc.), let's conservatively assume a flat $1000 per person in lost productivity.
Thus, the conservative total cost for Trump's deportation boondoggle as stated will be:
10M x $10K X $1K = $1 X 10^14 = $100 trillion.
By comparison, total annual budget of the US government is only around $6 trillion. Total GDP for 2023 was less than $30 trillion.
Needless to say, millions of workers and $100 trillion taken out of the US economy will trigger a global recession and is simply not practical or reasonable. In other words, you were lied to. It ain't happening --- except for perhaps a few examples done mainly for show.
Maybe Mexico will pay for it.
