Economies need investment (purposefully thought out ideas) not random spending on what is already there.?

Spending does not create growth. If you spend more it does not equate to more production. If this was true, we could just print money when times where bad. But we all know all that does is create inflation. Growth happens when people become more productive and capital is freely flowing. Aside from these 2 things, nothing else matters economically. The "rules" often hamper growth, viz min wage. Min wage help no one, it just creates unemployment.
