As I said, very few people have any real understanding of the macro-economy. The only relevant demand is the demand for the stuff you sell, or intend to sell. If there is no demand for four cylinder riding lawnmowers, it doesn't how much corporate taxes are cut, or how much expendable income increases. You aren't going to sell anymore lawnmowers and you certainly aren't going to add another assembly line to make more.
I'm afraid that list doesn't include you.
No investment, they aren't going to add the assembly line no matter how many people want mowers. You'll just get inflation instead.
Next, we'll analyze the sequence of chicken and egg production.
However, before that, please explain why a company would invest in capital improvements, if they did not believe demand existed for increased production. In the meantime, my statement on macro-economics remains unchallenged.
Demand is necessary for me to invest capital but not sufficient.
Let's say I'm thinking about drilling an oil well. I have no doubt that the demand exists for the oil. What I don't know is whether I can earn enough return to offset the risk.
The risks include 1) the well might cost more than I estimate, 2) the oil price I receive might be lower than I estimate, 3) I might not get as much oil as I estimate
Whether the government says "I'm going to take a) 0% b) 50% or c) 90% of your profit" affects my return quite a lot but does not affect the risks much - except to the extent vendors pass on their additional costs in their service rates.
Lower return, same risk means less capital gets invested.
