I'm not sure if this is changing or whether it never really changed (in the past 50 years or so): professionals using tools just have no need for tools which might break quickly so there always has been (at least in my memory) a market segment for proper tools (high end think Festool, Hilti, ... but even somewhat lower end tools never seemed to had problems like becoming unusable/unrepairable within a couple of years). And even though some small segment of the market might now be taken over by ultracheap less decent tools, the segment with the decent tools is still going strong as ever.
