A provision in tax code letting companies expense investments in US including R&D in 5 years expired in 2022. For budget reasons it was not renewed. The DJT Big Beautiful Bill lets US companies expense R&D in 1 year compared to the 15 years in overseas investments. This is leading to a surge in R&D investment and hiring by companies. Fed's Powell sees this as one of the big positive factors for the US economy in 2025-2028.
The change lowers cost of hiring by 20-25% and this means more engineers and other people are going to be hired.
