Your OP makes sense however in theory. Balance is a big factor...
* My home is actually my investment, if I have any extra money that is where I will invest it (monthly if at all possible). Through the years, I noticed that my mortgage payments has slowly dropped year after years and that the price of my house along with the cost of renting an apartment went the total opposite way. So, I figure I save big time
* I made a decision few years back and stay loan free. IE: I have not bought any new cars for close to 10 years now and simply buy a used car I can trust, pay the car completely through my credit card and make sure I repay before the deadline (my last one was bought 2 years ago and finally it costed me 50$ on top of the car cost since I couldn't make the deadline fully)
* As a consumer, I buy stuff according to my means and again will use the CC if I can't fully pay for the purchase but again make sure it is re-paid before the deadline. I also use free credit from the store which provide me a few months to repay without interest. I can then dump that money on the mortgage and of course repay the credit before the deadline.
* It can sometime take me a couple years to acquire the object of my dream since I want to make sure it is budget friendly for me. IE: I wanted HT recliners for a couple years now, missed some great sales :( but finally got the 2 3 seaters delivered last week, acquired them at sale pricing (1/2 price) and have 7 months to pay for them. The nice thing, I figured I will more likely be able to dump a minimum of 600$ on the mortgage by the end of the month (Yeah, in 2 days :D )
* Acting in such a way, gives me extra financial power years after years. Maybe some day, I'll be able to afford High End gear versus the mid level gear my modest means has dictated me to acquire through the years
So, your OP makes a lot of sense but it is simply a matter of balance and planning. I am convinced while the way I spend the money is good for my finance I realize I am probably making some mistakes once in a while but the overall picture of my finance is looking healthier day after days. Balance is the key, not to spend above your means while not having the belt so tight you can't enjoy life.
Cheers!
