> To preserve relative margins companies need to increase prices by 145%.

Not true. If you have watched Shark Tank you have seen that products cost, as an example, $6 landed, but retail for $24. Tariffs are 145% of $6, so around $9. So they only have to increate the retail price from $24 to $33 to keep the same profit margin. In this example that's a 37% increase, not 145%.
