cool beans.... I'll respond to ya when you get a chance to post again. But as a parting thought I will offer that there is alot of profit to be made when investing in consumables :~ D
Spending for consumption sustains the current level of production but doesn't add new capability. To do that we need investment. I'm not knocking spending, it's a big part of our economy and many industries and services have been built to support the retail industry such as delivery, accounting, and loads of online services and support. But spending can be too big a part of an economy as ours is now. We should be producing more exportable goods as a share of the economy rather than going into debt to support consumption.
Saving and investing on the other hand is deferred consumption. Instead of taking some goods in trade for my services, I take money which I save or invest so I can buy the goods later. Investment (such as buying new production machinery) is also the primary way to improve productivity. That allows more people to be hired and higher wages to be paid. Workers who are motivate to work harder will also produce more as you point out. But the productivity increases produced by investment vastly outpace any gains by working harder. The machinery and automation brought by information technology had produced amazing increases in productivity which has lead to greater wealth overall. I admit sometimes the wealth takes a while to trickle down especially when old manufacturing methods are being phased out and workers need to be retrained. But holding back those improvement to protect jobs will result in lost jobs overall as the wealth and productivity of the economy is reduced.
