Not at all!

It only redistributes work toward what rich people want.

Investing into something actually useful would be much better.

Scenario A: yacht is bought - economy is redirected toward luxurious yacht building, people get paid to work on building a yacht

Scenario B: investment into housing - economy is redirected toward house building, people get paid to build houses

scenario A can be a good one only when this people would be unemployed and seeking a work otherwise. Or if you think that building luxurious yachts is more important than alternatives.
