Assume
1 you are USA based
2 you do get the 2000 in tariff money trump has mentioned.
That's a very difficult assumption mainly because of two things.
First is that the cost of living is not as extremely high as it is in the US so $2000 would go a much longer way than it would for an American, since for example a gallon of gas that costs an American $3-$4 would cost me $0.05.
Second is that most economies in the word are not debt based like the US economy so people in most of the world are not up to their necks in debt, therefore they have an easier time investing any "extra" money they get their hands on.
In any case, what would I do? I would put another 2 grand on top and buy bitcoin. Specially now that we are getting a discount thanks to the weak hands who sold and pushed the price a little lower...

JUST filled my hybrid at $2.89 a gallon .
A nickel a gallon would be very nice.
My bills to live in a first world country are amazing.
Property tax 10,000 a year.
Car insurance 3,000 a year
Health insurance 14,000 a year
