No it wasn't. The tax laws were changed to give companies "incentives" to return capital/jobs to the US (which we know they never do in the long term).

The tax law reduced our corporate taxes to their lowest levels in recent history. They also lowered the average person's taxes, but only temporarily (they will be rising over the next 5-6 years). And then they created new schemes, such as the business owner pass thrus. And I think they lowered the capital gains tax (don't quote me on that one).

The only somewhat positive thing they implemented was a one-time tax on corporate earnings overseas. This was used to help pay for some of the tax breaks they gave companies, but also offset the total cost of the bill. This encouraged the companies to repatriate their overseas earnings since they were going to be taxed anyways. Thought was, if they bring the money home, they'll invest in the US economy - except they said they wouldn't and then they didn't - they gave their shareholders dividend increases and stock buybacks...

Global minimum taxes were never on the table in 2017. That is a recent phenomenon...
