I find about the same percentage of people are do it yourselfers as always have been.
Over the years, us fix-it folks tend towards things that were designed to be fixed. Still plenty of those around. I can't drive 5 miles without passing a line of tractors in a row along a field - and everyone of them was originally designed to be fixed.
Luckily, there still isn't any law in the land that says tools in a workshop must be new, - and that goes equally for tractors, trucks, cars, appliances, implements, or even one's house & barn. Over the years these have all become old enough to be fixable - and stay as useful as they were originally.
Ingenuity coupled with ambition and a bit of self-education seem to be a the real answer to inflation.
